Coalbed methane (CBM) is an important resource in the world, and CBM power generation is supposed as the most effective method to make utilization of the low-concentration methane. In this context, efficient nitrogen oxides (NO_x) removal is of paramount importance, where the long-term stable operation of zeolite catalyst is significantly challenged under high temperature, high NO_x concentration, high humidity, and high gas hourly space velocity conditions (abbreviated as ‘four high’). Herein, in view of the characteristics of exhaust gas, potential reactions that occurred including ammonia-selective catalytic reduction (NH₃-SCR), hydrocarbon-selective catalytic reduction (HC-SCR), carbon monoxide-selective catalytic reduction (CO-SCR), the competitive oxidation reaction between CH₄ and CO are reviewed in detail, such as the catalysts, influencing factors and reaction mechanisms. Besides the excellent NO_x conversion, anti-aging, anti-poisoning, and anti-sintering performance are essential in this field. Furthermore, preparing the low-cost zeolite derived from solid waste represents an efficient and promising integration the disposal of coal fly ash and coal gangue, as well as the removal of NO_x. This review not only proposes the theoretical system and construction strategy of denitrification catalysts, but also contributes the theoretical basis for efficient NO_x removal of the CBM power generation, and collaborative control of gas pollution in accordance with ‘treating exhaust with gas’ and ‘treating exhaust with coal’ guidelines.

煤层气是世界上重要的资源，煤层气发电被认为是利用低浓度甲烷最有效的方法。在这种情况下，高效去除氮氧化物（NOx）至关重要，因为沸石催化剂在高温、高NOx浓度、高湿和高气体小时空速条件下（简称“四高”）的长期稳定运行受到极大挑战。本文针对废气的特点，对可能发生的氨选择性催化还原（NH3-SCR）、烃类选择性催化还原（HC-SCR）、一氧化碳选择性催化还原（CO- scr）、CH4与CO之间的竞争性氧化反应，如催化剂、影响因素和反应机理等进行了详细的综述。除了优异的NOx转化性能外，抗老化、抗中毒和抗烧结性能在该领域也是必不可少的。此外，从固体废物中制备低成本的沸石是一种高效且有前途的综合处理粉煤灰和煤矸石以及去除氮氧化物的方法。本综述不仅提出了脱硝催化剂的理论体系和构建策略，而且为煤层气发电高效脱除NOx、按照“以气治排”和“以煤治排”方针协同治理燃气污染提供了理论依据。

With the increasing global concern for environmental issues and sustainable development, photocatalytic technology has significant promise in addressing environmental contamination and energy shortages. This technology utilizes renewable solar energy as an energy source and produces no harmful by-products. Notably, selecting suitable photocatalysts is the key to achieving efficient photocatalysis. Homojunction photocatalysts, consisting of elements with the same semiconductor material but different crystalline phases/exposed surfaces/dimensions, have garnered significant interest recently. The reason is that near-perfect lattice matching at the homojunction interface and continuous band bonding greatly facilitate photogenerated charge transport. Furthermore, the internal electric field in the homojunction well drives the migration and separation of photoinduced charge carriers, improving photocatalytic activity. Herein, this review summarizes the recent advances in homojunction photocatalysis, introduces the fundamentals of different homojunction photocatalysts, and focuses on the preparation methods of homojunction photocatalysts and their photocatalytic applications in energy production and environmental protection, such as reducing CO₂, producing H₂, fixing N₂, and degrading pollutants.

The limitations of membrane filtration processes in water and wastewater treatment have led to the development of photocatalytic membranes. These membranes are produced by integrating photocatalytic and membrane filtration technologies. Developing photocatalytic membranes with anti-fouling and self-cleaning capabilities is essential for these applications. Utilizing photocatalysts with high photocatalytic activity and excellent hydrophilic properties is advantageous. Among various semiconductor photocatalytic materials, layered double hydroxides (LDHs) stand out due to their hydrophilicity, large surface area, adjustable interlayer spacing, and robust photocatalytic performance. However, limitations such as electron-hole recombination and low visible light absorption reduce the photocatalytic activity of LDHs. A common method to enhance the photocatalytic properties of LDHs is by forming heterostructures with other semiconductor materials. LDH-based heterostructures with improved photocatalytic properties are promising for enhancing photocatalytic membrane performance. This review comprehensively examines recent advancements in photocatalytic membranes modified with LDH-based heterostructures for water and wastewater treatment, offering a clear perspective for researchers in the field.

膜过滤工艺在水和废水处理中的局限性导致了光催化膜的发展。这些膜是通过整合光催化和膜过滤技术生产的。开发具有抗污染和自清洁能力的光催化膜对这些应用至关重要。利用光催化活性高、亲水性好的光催化剂是有利的。在各种半导体光催化材料中，层状双氢氧化物（LDHs）因其亲水性、大表面积、层间间距可调和强大的光催化性能而脱颖而出。然而，电子-空穴复合和低可见光吸收等限制降低了LDHs的光催化活性。提高LDHs光催化性能的常用方法是与其他半导体材料形成异质结构。具有改进光催化性能的ldh基异质结构在提高光催化膜性能方面具有广阔的前景。本文综述了近年来ldh基异质结构光催化膜在水和废水处理方面的研究进展，为该领域的研究人员提供了一个清晰的前景。

Photocatalytic CO₂ reduction reaction (CO₂RR) is one of the strategies to mitigate the greenhouse effect, in which the generation of CH₄ as a high-calorific-value clean energy source has attracted much attention. Among many photocatalysts, titanium dioxide (TiO₂) is more attractive due to its controllable energy band structure and other advantages. However, its wide forbidden band leads to low light utilization and catalytic capacity. Therefore, tuning the energy band structure and absorbance range of TiO₂ to improve CO₂RR efficiency has become a research focus. On the basis of few reviews on the research progress of photocatalytic CO₂RR to CH₄ from TiO₂-based composites, this paper firstly comprehends the principle and reaction pathway of photocatalytic CO₂RR, and introduces the influence of the dosage of the main reactants (H₂O and CO₂) on the photocatalytic process, as well as the preparation method of the TiO₂-based catalysts. Then the research progress of TiO₂-based catalysts in the field of CO₂RR to CH₄ photocatalysis (e.g., construction of TiO₂ heterojunction, surface modification, elemental doping, metal-organic frameworks (MOF)/TiO₂, etc.) is reviewed, which provide guidance for the design of photocatalysts with excellent performance. Finally, challenges and research opportunities are discussed and outlooked.

光催化CO2还原反应（CO2RR）是缓解温室效应的策略之一，其中生成CH4作为一种高热值的清洁能源备受关注。在众多光催化剂中，二氧化钛（TiO2）因其能带结构可控等优势而备受青睐。但其禁带较宽，导致光利用率和催化能力较低。因此，调整TiO2的能带结构和吸光度范围以提高CO2RR效率已成为研究热点。本文在对tio2基复合材料光催化CO2RR制CH4的研究进展进行综述的基础上，首先了解了光催化CO2RR的原理和反应途径，并介绍了主要反应物（H2O和CO2）用量对光催化过程的影响，以及tio2基催化剂的制备方法。然后综述了TiO2基催化剂在CO2RR - CH4光催化领域的研究进展（如TiO2异质结的构建、表面改性、元素掺杂、金属有机框架(MOF)/TiO2等），为设计性能优异的光催化剂提供指导。最后，对挑战和研究机遇进行了讨论和展望。

Electrochemical degradation is a sophisticated and environmentally sustainable method for treating hazardous substances in water and wastewater. This technique uses electrical energy to facilitate the oxidation and reduction of contaminants, converting them into less damaging or inert by-products. The approach is adaptable and proficient at degrading diverse contaminants, encompassing organic chemicals, heavy metals, and enduring pollutants such as pesticides and medicines. Principal advantages encompass elevated efficiency, enhanced controllability, and elimination of supplementary chemicals. Analytical methods, including High-Performance Liquid Chromatography (HPLC) and Gas Chromatography-Mass Spectrometry (GC-MS), are utilized to assess degradation rates, examine the degradation process, identify by-products, and confirm removal efficacy. Application of metal oxide nanoparticles, metal oxide-based carbon nanostructures, granular activated carbon (GAC) as cost-effective material, and MXene demonstrated significant removal efficiency when optimum analytical parameters such as pH, charge density, suitable electrolyte, and degradation time were employed. Self-cleaning electrodes, ultrasonic cleaning devices, or flow-through systems may mitigate the fouling problem in the analysis. Utilization of advanced materials such as boron-doped diamond (BDD) or titanium suboxide (TiSO) exhibits higher corrosion and degradation resistance. Employ protective coatings on electrodes to prevent direct exposure to aggressive pollutants, thereby prolonging the lifespan of the electrodes. Current research aims to enhance electrode materials, improve process efficiency to reduce initial costs and combine sustainable energy sources with electrochemical systems to minimise power consumption, positioning electrochemical degradation as a viable approach for sustainable environmental remediation.

A novel catalytic system employing a modified fly ash catalyst doped with bimetal oxides has been investigated for its efficacy in selective catalytic reduction (SCR) with ammonia (NH₃) to reduce NO_x pollutants. The study reveals the synergistic interaction between two activate agents, copper (Cu) and manganese (Mn), on fly ash (FA), achieving impressive NO_x removal efficiency. The best-performing catalyst, FA/Cu/Mn-5, is composed of 90 % fly ash, 5 % copper, and 5 % manganese. It removes 98.5 % of NO_x at 200°C. Copper oxide (CuO) helps speed the reaction by converting nitrogen monoxide (NO) into nitrogen dioxide (NO₂), an important part of the SCR process. Manganese oxide (MnO₂), an enhancer of oxygen availability, can promote NH₃ oxidation, effectively lowering the operational temperature and mitigating the formation of nitrous oxide (N₂O). This contrasts with previous research, which reported significant N₂O generation, a major greenhouse gas. Therefore, this current study offers a more sustainable approach to emission control. This study also highlights the critical role of reactive intermediates, such as NO₂, in driving the SCR mechanism, underscoring the potential of modified fly ash catalysts to combat air pollution effectively.

研究了掺有双金属氧化物的改性粉煤灰催化剂在氨（NH3）选择性催化还原（SCR）中还原NOx污染物的效果。该研究揭示了两种活化剂铜（Cu）和锰（Mn）在飞灰（FA）上的协同作用，实现了令人惊叹的NOx去除效率。性能最好的催化剂FA/Cu/Mn-5由90% %粉煤灰、5 %铜和5 %锰组成。在200℃下，它能脱除98.5% %的NOx。氧化铜（CuO）有助于加速反应，将一氧化氮（NO）转化为二氧化氮（NO2），这是SCR过程的重要组成部分。氧化锰（MnO2）作为氧可用性增强剂，可以促进NH3氧化，有效降低操作温度，减缓氧化亚氮（N2O）的生成。这与之前的研究形成了对比，之前的研究报告了一种主要的温室气体N2O的产生。因此，本研究提供了一种更可持续的排放控制方法。该研究还强调了活性中间体（如NO2）在驱动SCR机制中的关键作用，强调了改性粉煤灰催化剂有效对抗空气污染的潜力。

This review article assesses the performance of various adsorbents for CO₂/CH₄ separation, a critical step in the final phase of a biogas upgrading plant. The focus is particularly on the use of pressure swing adsorption (PSA) units for this purpose. Four types of adsorbents, including activated carbons (ACs), carbon molecular sieves, metal organic frameworks, and zeolites, are thus evaluated based on their selectivity in CO₂/CH₄ separation and PSA working capacity ratio. This selectivity is estimated from pure component isotherms through the Ideal Adsorbed Solution Theory (IAST), and the PSA working capacity ratio is evaluated for a PSA cycle with depressurization at atmospheric and sub-atmospheric pressure. The results show that ACs exhibit the lowest selectivity, while zeolites have the highest selectivity and PSA working capacity ratio. The article also includes a review of simulation studies on CO₂/CH₄ separation by PSA. In addition, PSA units are compared based on their productivity, energy consumption, purity, and recovery. To calculate energy consumption and productivity, parameters that are often overlooked, a mass balance is applied to the PSA cycle described in each relevant literature study. Our study suggests that the PSA cycle with pressure equalization and sub-atmospheric pressure depressurization is the most optimal, providing valuable insights into the selection and optimization of adsorbents and PSA units for CO₂/CH₄ separation.

本综述文章评估了各种吸附剂在 CO2/CH4 分离方面的性能，这是沼气升级工厂最后阶段的关键步骤。重点尤其放在变压吸附 (PSA) 装置的使用上。因此，根据四种吸附剂（包括活性炭 (AC)、碳分子筛、金属有机框架和沸石）在 CO2/CH4 分离中的选择性和 PSA 工作容量比，对它们进行了评估。这种选择性是通过理想吸附溶液理论（IAST）从纯组分等温线中估算出来的，而 PSA 工作容量比则是在大气压和次大气压下进行减压的 PSA 循环中评估出来的。结果表明，AC 的选择性最低，而沸石的选择性和 PSA 工作容量比最高。文章还回顾了利用 PSA 分离 CO2/CH4 的模拟研究。此外，还根据生产率、能耗、纯度和回收率对 PSA 装置进行了比较。为了计算能耗和生产率这些经常被忽视的参数，我们对每篇相关文献研究中描述的 PSA 循环进行了质量平衡。我们的研究表明，具有压力均衡和亚大气压减压功能的 PSA 循环是最理想的，这为选择和优化用于二氧化碳/CH4 分离的吸附剂和 PSA 装置提供了宝贵的见解。

The widespread detection of per- and polyfluoroalkyl substances (PFAS) in aqueous environment has emerged as a global concern due to their persistent nature, high stability, and potential toxicity. Thus, in the recent decades, removal of PFAS from water matrices has garnered tremendous attention of researchers to combat this pervasive environmental threat and mitigate the risk imparted by these toxic compounds on living beings and the environment. In this context, this critical review elucidates different technologies based on their removal mechanisms, either separation or degradation, employed for the remediation of PFAS from water matrices. This review also emphasizes on techno-economic analysis (TEA) and life cycle assessment (LCA) of the discussed technologies for evaluating their practical feasibility before deploying them on the field for remediation of PFAS, which are generally overlooked while comparing different technologies. The strength-weakness-opportunity-threat (SWOT) analysis of discussed technologies is also presented in this article, with the aim to provide insight into underlying opportunities and challenges with these technologies, thus beneficial in electing the best technology for PFAS remediation. This paper also highlights the current challenges, limiting the application of these technologies at the field-scale that necessitate further efforts and can be further translated into plausible future research opportunities. In a nutshell, this paper intends to guide the researchers by presenting a systematic review of different technologies employed for PFAS remediation by critically comparing these technologies through SWOT analysis along with their LCA and TEA, enabling scientists to identify the most effective, sustainable, and economically feasible PFAS remediation technology.

The global epidemic of COVID-19 has intensified the urgency for the development of high-efficiency air filters with antiviral and antibacterial properties. While conventional commercial air purifiers can filter particulate matter, they often fall short of eradicating airborne pathogens. Thus, there is a critical need to innovate air filtration systems capable of not just trapping but exterminating harmful microorganisms to impede their airborne transmission. One potential solution is to use antibacterial photodynamic technique (aPDT). Indeed, recent years have witnessed the rapid growth in this area. This review summaries applications of aPDT for air disinfection through the inactivation of bacteria, fungi, and viruses. In addition, the mechanisms of photosensitizer-assisted pathogen inactivation and the futher development in photodynamic air disinfection technique are also discussed.

COVID-19 在全球的流行加剧了开发具有抗病毒和抗菌特性的高效空气过滤器的紧迫性。虽然传统的商用空气净化器可以过滤微粒物质，但往往无法根除空气中的病原体。因此，亟需创新空气过滤系统，使其不仅能捕捉有害微生物，还能消灭它们，从而阻止它们在空气中传播。一种潜在的解决方案是使用抗菌光动力技术（aPDT）。事实上，近年来这一领域发展迅速。本综述总结了通过灭活细菌、真菌和病毒对空气进行消毒的 aPDT 应用。此外，还讨论了光敏剂辅助灭活病原体的机制以及光动力空气消毒技术的未来发展。
