Among emerging solutions, CO₂ conversion technologies offer a transformative pathway by enabling the utilization of CO₂ as a renewable carbon feedstock for the production of fuels, chemicals, and materials, thereby promoting a circular carbon economy. The review begins by exploring foundational CO₂ capture and pre-treatment methods, emphasizing advanced materials, as well as integration strategies that directly couple capture with conversion processes as a gateway to improved CO₂ conversion. Recent advancements in CO₂ conversion technologies, spanning thermochemical, electrochemical, photochemical, and biological domains are then covered. The integration of CO₂ conversion systems with renewable energy and industrial infrastructures is explored through case studies and commercialization efforts, highlighting opportunities for sector-wide decarbonization.

The importance of carbon capture, utilization, and storage (CCUS) for achieving carbon neutrality is increasingly recognized. Carbonate minerals are currently being manufactured from the abundant calcium-containing wastes and minerals that are generated by carbon mineralization technology in industry. Among these, calcium carbonate, which is highly versatile, generally exists in three crystal forms (vaterite, aragonite, and calcite). These three crystal forms must be freely controllable to increase the value and range of use of calcium carbonate. In this study, the variables of concentration, temperature, pH, stirring speed, and stirring time were changed during the reaction of calcium raw material (i.e., CaCl₂) and carbon raw material (i.e., K₂CO₃). In addition, the phase composition ratios were determined by Rietveld refinement analysis using X-ray diffraction (XRD) patterns. Drawing on an extensive set of experimental data, we constructed data-driven predictive models by training and evaluating multilayer perceptron (MLP), support vector machine (SVM), random forest (RF), and decision tree (DT) algorithms. The best-performing model, selected by k-fold cross-validation, was then applied to determine the optimal operating conditions to control crystallinity. This study provides comprehensive knowledge about a system that allows industries to select, manufacture, and produce calcium carbonate in the crystal form they need. It is anticipated that using carbon mineralization technology, which is part of CCUS technology, will contribute to carbon neutrality, while alleviating waste environmental treatment costs.

碳捕获、利用和封存（CCUS）对实现碳中和的重要性日益得到认识。碳酸盐矿物是目前工业上利用碳矿化技术产生的大量含钙废物和矿物制造的。其中，用途广泛的碳酸钙，一般以三种晶体形式存在（水晶石、文石和方解石）。这三种晶型必须是自由可控的，以增加碳酸钙的价值和使用范围。在本研究中，改变了钙原料（即CaCl2）和碳原料（即K2CO3）在反应过程中的浓度、温度、pH、搅拌速度和搅拌时间等变量。此外，采用x射线衍射（XRD）图，通过Rietveld细化分析确定了相组成比。利用大量的实验数据，我们通过训练和评估多层感知器（MLP）、支持向量机（SVM）、随机森林（RF）和决策树（DT）算法，构建了数据驱动的预测模型。然后通过k-fold交叉验证选择最佳模型，以确定控制结晶度的最佳操作条件。这项研究提供了一个系统的全面知识，允许工业选择，制造和生产碳酸钙的晶体形式，他们需要。预计使用碳矿化技术（CCUS技术的一部分）将有助于碳中和，同时降低废物环境处理成本。

Direct Air Capture (DAC) and Post-Combustion CO₂ capture (PCC) using liquid and solid amine sorbents, received enormous attention due to worsening weather and climate change. Enhancing the efficiency of CO₂ capture and removal technologies is crucial, with a primary focus on reducing the energy demand for continuous capture-release cycles. Low-energy CO₂ removal strategies offer promising durability and low operational costs, and a low levelized cost per ton of CO₂ removal is preferred for large-scale implementation. This review highlights low-energy CO₂ removal approaches, such as moisture/humidity swing sorbents. This discussion covers the influence of structural and molecular characteristics, the effect of counter anions on CO₂ removal efficiency and kinetics, the impact of different operational factors on performance, and the long-term stability of these materials. Continuous exploration and optimization of these materials and methods are vital for advancing the moisture swing method, contributing to global efforts to combat climate change and promoting environmental sustainability. Finally, recommendations are provided for the design of innovative materials.

The increasing CO₂ concentration in atmosphere leads to significant ecological changes, and the control of CO₂ emissions has been a major concern worldwide. Amine-functionalized adsorbents are promising because they have high CO₂ adsorption capacity, moderate adsorption heat and strong water resistance. Adsorption kinetics is a key performance parameter and facilitates the cognizance of microscopic CO₂ adsorption process. A novel kinetic model was proposed, which categorized the amines of solid amine adsorbents into two regions: the open amine region and the closed amine region. Different from the open amine region, CO₂ adsorption by amines in the closed amine region was significantly influenced by diffusion. The model could elucidate the effect of amine loading and temperature on CO₂ adsorption. When amine loading was below the theoretical maximum loading, the CO₂ adsorption capacity and the N efficiency gradually increased with the rise of amine loading. Nevertheless, as the amine loading further increased, the adsorption capacity decreased instead. CO₂ adsorption by solid amines was not affected by external diffusion, but was significantly affected by internal diffusion. The percentage of closed amine region of adsorbents with high amine loading was large, CO₂ needed to diffuse slowly into this region, leading to a small CO₂ adsorption capacity at low temperature. When the amine loading was less than 0.5, the CO₂ adsorption rate stayed almost the same. The model is instructive for the targeted preparation of solid amine adsorbents with fast adsorption rates.

大气中CO2浓度的增加导致了重大的生态变化，CO2排放的控制一直是世界各国关注的焦点。胺功能化吸附剂具有高的CO2吸附能力、适中的吸附热和较强的耐水性等优点，具有广阔的应用前景。吸附动力学是一个关键的性能参数，有利于微观CO2吸附过程的认识。提出了一种新的动力学模型，将固体胺吸附剂中的胺分为两个区域：开放胺区和封闭胺区。与开放胺区不同，封闭胺区对CO2的吸附受扩散的影响较大。该模型能较好地阐明胺的负载和温度对CO2吸附的影响。当胺负荷低于理论最大负荷时，随着胺负荷的增加，CO2吸附量和氮效率逐渐增加。然而，随着胺负荷的进一步增加，吸附量反而下降。固体胺对CO2的吸附不受外部扩散的影响，但受内部扩散的影响较大。高胺负荷吸附剂封闭胺区所占比例大，CO2需要缓慢扩散到该区域，导致低温下CO2吸附量小。当载胺量小于0.5时，CO2吸附率基本保持不变。该模型对定向制备快速吸附的固体胺吸附剂具有指导意义。

Flowback and produced water (FPW) from hydraulic fracturing operations of tight hydrocarbon reservoirs has attracted significant research interest, particularly regarding its treatment and the recovery of valuable minerals. In this study, a simple and sustainable method was developed to precipitate calcium (Ca), magnesium (Mg), and strontium (Sr) carbonates from a high salinity FPW using NH₃ or NaOH and CO₂-containing flue gas. The precipitated solids and the treated FPW solution were subjected to various characterization techniques to evaluate the properties of the solids and the efficiency of the precipitation method. The precipitated carbonate minerals were further investigated as sorbents for CO₂ capture in the calcium looping process, demonstrating a substantial carbon capture capacity of approximately 0.3 kg CO₂/kg solid sample. Moreover, a series of detailed process simulations and economic analysis were performed to further evaluate the potential of using solid precipitates from FPW in the calcium looping process. Two different operating modes and multiple cases of calcium looping using solid sorbents from FPW, integrated with renewable energy, were thoroughly studied. The economic analysis of this integrated technology showed a relatively comparable levelized cost of carbon capture, at less than $200 per tonne of CO₂ captured. The techno-economic analysis of the overall process demonstrated the potential of the calcium looping process with carbonate precipitates from produced water as a possible approach for decarbonization and energy transition in the oil and gas industry.

致密油气储层水力压裂返排和采出水（FPW）引起了人们极大的研究兴趣，特别是在其处理和有价值矿物的回收方面。在本研究中，开发了一种简单且可持续的方法，利用NH3或NaOH和含二氧化碳的烟气从高盐度FPW中沉淀钙（Ca）、镁（Mg）和锶（Sr）碳酸盐。对沉淀固体和处理后的FPW溶液进行了各种表征技术，以评估固体的性质和沉淀方法的效率。进一步研究了沉淀的碳酸盐矿物作为钙环过程中二氧化碳捕获的吸附剂，证明了大约0.3 kg CO2/kg固体样品的可观碳捕获能力。此外，还进行了一系列详细的过程模拟和经济分析，以进一步评估在钙循环过程中使用FPW固体沉淀物的潜力。对FPW固体吸附剂与可再生能源相结合的两种不同操作模式和多例钙循环进行了深入研究。对这一综合技术的经济分析表明，碳捕获的成本相对相当，每捕获一吨二氧化碳不到200美元。对整个过程的技术经济分析表明，利用采出水中的碳酸盐沉淀物进行钙环工艺的潜力，可能是石油和天然气行业脱碳和能源转型的一种方法。

Morphological changes of natural limestone-based CO₂ sorbents during the cyclic transition between CaO and CaCO₃ affect their carbonation rate and cyclic CO₂ uptake. We examine the evolution of the pore structure of Havelock limestone during carbonation in the ranges (I) 2–100 nm, (II) 200–3000 nm and (III) > 3000 nm with unprecedented detail, and correlate morphological changes with the observed carbonation rate. Pores of region (I) are fully filled with CaCO₃ at a CaO conversion > 60 % (1st cycle), leading to a loss of ∼ 90 % of the total surface area of the sorbent, whereas pores of region (II) are only partially filled, and pores of region (III) remain largely unaffected. Throughout the carbonation reaction in the 1st and 10th cycle, the observed carbonation rate decreases linearly with the decreasing total surface area of the sorbent. Supported by kinetic and morphological modelling, our findings challenge the widely used concept of a CaCO₃ product layer of critical thickness limiting CO₂ diffusion to CaO, implying that the reaction is limited by diffusion as soon as the surface of CaO is fully covered with CaCO₃ crystallites. Our results further provide a perspective on the design of efficient CaO-based sorbents by tuning their pore diameter to be larger than > 100 nm, such that the pore volume (and the respective surface area) can be largely regenerated over cycling, in turn yielding a high cyclic CO₂ uptake.

天然石灰石基CO2吸附剂在CaO与CaCO3循环过渡过程中的形态变化影响其碳化速率和循环CO2吸收量。我们以前所未有的细节研究了Havelock灰岩在(I) 2-100 nm、（II） 200-3000 nm和（III） 3000 nm范围内碳酸化过程中孔隙结构的演化，并将形态变化与观测到的碳酸化速率联系起来。区域(I)的孔隙被CaCO3完全填充，CaO转化率为>； 60%（第1循环），导致吸附剂总表面积损失约90%，而区域（II）的孔隙仅被部分填充，而区域（III）的孔隙基本不受影响。在第1和第10个循环的碳化反应中，观察到的碳化速率随着吸附剂总表面积的减小而线性减小。在动力学和形态学模型的支持下，我们的发现挑战了广泛使用的CaCO3产物层的临界厚度限制CO2向CaO扩散的概念，这意味着一旦CaO表面完全被CaCO3晶体覆盖，反应就会受到扩散的限制。我们的研究结果进一步为设计高效的cao基吸附剂提供了一个视角，将其孔径调整到大于100 nm，这样孔隙体积（和相应的表面积）可以在循环过程中大量再生，从而产生高循环二氧化碳吸收率。

Our results further provide a perspective on the design of efficient CaO-based sorbents by tuning their pore diameter to be larger than > 100 nm, such that the pore volume (and the respective surface area) can be largely regenerated over cycling, in turn yielding a high cyclic CO<sub>2</sub> uptake.</div></div>","PeriodicalId":9387,"journal":{"name":"Carbon Capture Science & Technology","volume":"16 ","pages":"Article 100486"},"PeriodicalIF":0.0,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144879249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The development of cost-effective and efficient bifunctional materials is crucial for advancing integrated CO₂ capture and utilization (ICCU) technologies. Herein, we report the rational design of a cost-effective bifunctional composite, Ni nanoparticles dispersed on KNaTiO₃ (denoted as KR3) for CO₂ sorption and hydrogenation to CO. The KR3 derived from low-cost natural rutile sand was responsible for CO₂ sorption, while the uniformly dispersed nickel nanoparticles facilitated the transformation of sorbed CO₂ to CO. The formed bifunctional materials showed a CO₂ conversion of 76.7 % with near-perfect selectivity towards CO, and robust cyclic stability over 10 cycles. Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS) analysis revealed both the redox mechanism and formate reaction pathway existed in CO₂ hydrogenation to CO. The pelletized 10Ni/KR3 still exhibited decent CO₂ sorption capacity in the presence of O₂, and 84 % retention of CO₂ conversion was achieved in the hydrogenation process. The bifunctional 10Ni/KR3 material, distinguished by its high CO₂ sorption capacity, superior conversion activity, and robust cyclic stability, not only provides crucial insights for advancing solid CO₂ sorbents for flue gas capture and conversion but also demonstrates significant potential for practical carbon mitigation.

开发具有成本效益和效率的双功能材料对于推进二氧化碳综合捕集与利用（ICCU）技术至关重要。本文报道了一种低成本的双功能复合材料的合理设计，Ni纳米颗粒分散在KNaTiO3（表示为KR3）上吸附CO2并加氢成CO.从低成本的天然金红石砂中提取的KR3负责CO2的吸附，而均匀分散的镍纳米颗粒促进了吸附CO2向CO的转化。形成的双功能材料的CO2转化率为76.7%，对CO的选择性接近完美。并且在10个周期内具有很强的循环稳定性。漫反射红外傅立叶变换光谱（DRIFTS）分析表明，CO2加氢制CO过程中存在氧化还原机制和甲酸酯反应途径，在O2存在下，球团化的10Ni/KR3仍具有良好的CO2吸附能力，加氢过程中CO2转化率保持在84%。双功能10Ni/KR3材料以其高CO2吸附能力、卓越的转化活性和强大的循环稳定性而著称，不仅为推进用于烟气捕获和转化的固体CO2吸附剂提供了重要见解，而且还显示了实际碳减排的巨大潜力。

In recent years, dielectric barrier discharge (DBD) plasma-catalytic technology has emerged as a promising approach for CO₂ conversion due to its unique ability to activate inert molecules under mild conditions. This review systematically summarizes recent advances in DBD plasma-assisted catalytic processes for CO₂ utilization, focusing on four major technologies: CO₂ methanation, dry reforming of methane (DRM), CO₂ hydrogenation to methanol, and the reverse water-gas shift (RWGS) reaction. This review provides a comprehensive examination of DBD plasma-catalytic CO₂ conversion, with particular focus on process parameters, reaction mechanisms, and catalyst design strategies. The analysis highlights the crucial plasma-catalyst synergy, where non-equilibrium electron excitation from DBD plasma facilitates CO₂ dissociation while precisely engineered catalyst properties, including oxygen vacancies, tailor metal-support interactions, and direct the subsequent conversion pathways. These interdependent effects collectively determine their activity, selectivity, and stability. Additional emphasis is placed on plasma-assisted catalyst synthesis techniques and innovative approaches to mitigate carbon deposition, offering insights into the development of more efficient and durable catalytic systems for CO₂ conversion. This review affirms the technical viability and promising prospects of plasma-catalytic CO₂ conversion while acknowledging critical challenges in energy efficiency and product selectivity. To accelerate industrial translation, future research should focus on unraveling plasma-catalyst interactions through coupled in situ characterization and computational modeling, establishing fundamental structure-performance relationships under dynamic reaction conditions, and engineering scalable reactor systems that maintain catalytic integrity during continuous operation.

Intermediate-high temperature adsorbents are of interest as they can be used in process intensification and integrated CO₂ capture and conversion processes to couple gas separation with a chemical reaction. Herein we develop CaO-modified ZnO as a new intermediate-high temperature CO₂ adsorbent and show that the extent of CaO doping allows tuning of the CO₂ adsorption/desorption temperature as well as capture capacity. Five different adsorbents were synthesized with Ca loadings of 0 %, 1 %, 5 %, 10 %, and 15 % by weight on ZnO and tested via fixed bed reactor experiments and TGA-DSC. The highest adsorption capacity was found to be 0.73 mmol/g_cat for 5 %Ca/ZnO. The desorption temperatures for CO₂ was found to also be influenced by Ca loading. Adsorbents were characterised by XRD, SEM, TGA, BET and ICP-MS, to understand their structure it was determined that CaO deposits on ZnO pores as separate domains. Herein we develop CaO-modified ZnO as a novel intermediate-high temperature CO₂ adsorbent, demonstrating tuneable adsorption/desorption characteristics through CaO dispersion on a ZnO scaffold.

Sorption-enhanced steam reforming (SorESR) is an advanced thermochemical process integrating in-situ CO₂ capture via solid sorbents to significantly enhance hydrogen production and purity. By coupling CO₂ adsorption with steam reforming, SorESR shifts the reaction equilibrium toward increased H₂ yield, surpassing the limitations of conventional steam reforming (SR). The efficacy of SorESR critically depends on the physicochemical properties of the solid CO₂ sorbents employed. This review critically evaluates widely studied sorbents, including Ca-based, Mg-based, hydrotalcite-like, and alkali ceramic sorbents, focusing on their CO₂ capture capacity, reaction kinetics, thermal stability, and cyclic durability under SR conditions. Furthermore, recent progress in multifunctional sorbent-catalysts that synergistically facilitate catalytic steam reforming alongside CO₂ sorption is critically discussed. Moreover, the review summarises recent performance achievements and proposes strategies to improve sorbent capacity and reaction kinetics, thereby making the SorESR process more appealing for commercial applications. Large-scale SorESR implementation is expected to substantially increase hydrogen production efficiency while concurrently reducing CO₂ emissions and advancing sustainable energy technologies. This review offers novel insights into the development of advanced sorbent-catalyst systems and provides new strategies for enhancing SorESR efficiency and scalability for commercial H₂ Production.

吸附强化蒸汽重整（SorESR）是一种先进的热化学工艺，通过固体吸附剂进行原位CO2捕获，显著提高氢气产量和纯度。通过将CO2吸附与蒸汽重整相结合，SorESR使反应平衡朝着提高H产率的方向转变，突破了传统蒸汽重整（SR）的局限性。SorESR的效果主要取决于所采用的固体CO2吸附剂的物理化学性质。本文综述了广泛研究的吸附剂，包括ca基、mg基、类水滑石和碱陶瓷吸附剂，重点关注它们的CO2捕获能力、反应动力学、热稳定性和SR条件下的循环耐久性。此外，多功能吸附剂催化剂的最新进展，协同促进催化蒸汽重整与二氧化碳吸附进行了批判性的讨论。此外，综述总结了最近的性能成就，并提出了提高吸附剂容量和反应动力学的策略，从而使SorESR工艺更具商业应用吸引力。大规模实施SorESR有望大幅提高制氢效率，同时减少二氧化碳排放，推进可持续能源技术。这篇综述为先进的吸附剂-催化剂系统的发展提供了新的见解，并为提高SorESR的效率和商业制氢的可扩展性提供了新的策略。
