Antimony selenide (Sb₂Se₃) based heterojunction photocathodes have recently received an increased attention, largely due to their outstanding performances for hydrogen production through photoelectrochemistry (PEC) water splitting. The PEC water splitting process encompasses both physical and electrochemical processes. The physical process is capable of generating a photo-voltage, which can drive the photo-generated electrons transport to the electrode/electrolyte interface through the p-n junction. However, unlike traditional photovoltaic device, the protective layer and co-catalyst will also affect the electrical performance of device, resulting in a decrease in PEC performances and stability. How to optimize the electrical properties of the photoelectrode is a concern. In this work, devoted to Sb₂Se₃/TiO₂ photocathode structures, the photovoltaic performances of a photocathode were modeled and analyzed from three aspects: p-n junction, back contact, and transition layer between TiO₂ and co-catalyst, using the SCAPS-1D software and a realistic set of material parameters. Based on reported optimization strategy, tthe interface electrical characteristics of photocathode were studied by adjusting energy band, donor/acceptor density, defect density, electron affinity, and other parameters. A low-cost and easy to implement optimization strategy was proposed, which used Cd_1-xZn_xS as the buffer layer between p-n junctions, W-doped TiO₂ as the transition between TiO₂/co-catalyst, and Sn-doped Sb₂Se₃ as the back surface layer to suppress the carrier recombination. The optimized photocathode can theoretically obtain photoelectric conversion efficiency of 17.01%–17.14% and a maximum J_sc of 38.79 mA/cm², exhibiting the potential to obtain a large photocurrent in the photoelectrochemical water splitting process.

硒化锑（Sb2Se3）基异质结光电阴极近年来受到越来越多的关注，主要是由于其通过光电化学（PEC）水裂解制氢的优异性能。PEC水裂解过程包括物理过程和电化学过程。物理过程能够产生光电压，光电压可以驱动光产生的电子通过p-n结传输到电极/电解质界面。然而，与传统光伏器件不同的是，保护层和助催化剂也会影响器件的电性能，导致PEC性能和稳定性下降。如何优化光电极的电性能是一个值得关注的问题。本文以Sb2Se3/TiO2光电阴极结构为研究对象，利用SCAPS-1D软件和一组真实的材料参数，从p-n结、背接触和TiO2与共催化剂之间的过渡层三个方面对光电阴极的光伏性能进行了建模和分析。基于所报道的优化策略，通过调整能带、供体/受体密度、缺陷密度、电子亲和度等参数，研究了光电阴极的界面电特性。提出了一种低成本、易于实现的优化策略，即以Cd1-xZnxS作为p-n结之间的缓冲层，w掺杂TiO2作为TiO2/助催化剂之间的过渡层，sn掺杂Sb2Se3作为后表层抑制载子复合。优化后的光电阴极理论上可获得17.01% ~ 17.14%的光电转换效率和38.79 mA/cm2的最大Jsc，显示出在光电化学水分解过程中获得大光电流的潜力。

This study presents an exploration of bifunctional heterostructures of different photoactive materials with complementary attributes CuBi₂O₄/RGO/BiVO₄/Au for visible-light-driven photoelectrochemical water splitting. The materials swapping in sequential layering within the fabricated bifunctional photoelectrode CuBi₂O₄/RGO/BiVO₄/Au manifested a pivotal character in altering the dynamics of the photoelectrode from photoanode to photocathode. Among all designed photoelectrodes, CuBi₂O₄/RGO/BiVO₄/Au exhibited the highest current density (with UV cutoff filter (400 nm)) of 0.15 mA/cm⁻² at onset potential of 0.69V_Ag/AgCl with the maximum approach up to 0.25 mA/cm², and without UV cut-off filter - 0.50 mA/cm², verifying 50% evolution of oxygen and hydrogen within the less energetic and major portion of solar light. The incorporation of reduced graphene oxide (RGO) and CuBi₂O₄ with BiVO₄ resulted in enhanced catalytic output and rapid photogenerated charge mobility attributes during the visible-light-driven oxygen (OER) and hydrogen evolution (HER) reactions. In contrast, the introduction of Au nanoparticles to this heterojunction magnified the photogenerated electron generation by thermionic emission and tunneling, resulting in high efficiency of overall water splitting. The heterojunction CuBi₂O₄/RGO/BiVO₄/Au minimized the recombination rate of photogenerated electron-hole pairs and thus assisted charge separation by broadening the visible light absorption range. Under constant potential, the chronoamperometric measurements indicated the stable current flow over time and thus it facilitated the effective utilization of bifunctional CuBi₂O₄/RGO/BiVO₄/Au photoelectrode for sleek and expeditious solar-driven water splitting with 9.1 PEF%,0.036 ABPE%, 25 IPCE%, and 20 IQE%.

本研究探索了具有互补属性的不同光活性材料 CuBi2O4/RGO/BiVO4/Au 的双功能异质结构，用于可见光驱动的光电化学水分离。在所制造的双功能光电极 CuBi2O4/RGO/BiVO4/Au 中，材料的依次分层交换在改变光电极从光阳极到光阴极的动态过程中发挥了关键作用。在所有设计的光电极中，CuBi2O4/RGO/BiVO4/Au 在 0.69VAg/AgCl 的起始电位下显示出最高的电流密度（带紫外线截止滤光片（400 纳米）），为 0.15 mA/cm-2，最大值接近 0.25 mA/cm2，而不带紫外线截止滤光片时为 0.50 mA/cm2，这证明在能量较低的主要太阳光中，氧气和氢气的进化达到了 50%。在 BiVO4 中加入还原氧化石墨烯（RGO）和 CuBi2O4 可在可见光驱动的氧气（OER）和氢气进化（HER）反应中提高催化输出和快速光生电荷迁移属性。相比之下，在该异质结中引入金纳米粒子，通过热离子发射和隧道效应放大了光生电子的生成，从而提高了整体水分离效率。异质结 CuBi2O4/RGO/BiVO4/Au 将光生电子-空穴对的重组率降至最低，从而通过拓宽可见光吸收范围来帮助电荷分离。在恒定电位下，计时器测量结果表明电流随时间稳定流动，因此有助于有效利用双功能 CuBi2O4/RGO/BiVO4/Au 光电极来快速进行太阳能驱动的水分离，其 PEF 为 9.1%，ABPE 为 0.036%，IPCE 为 25%，IQE 为 20%。

The ammonia production is one of the most essential petrochemical processes. This article focuses on the heart of this process, the ammonia synthesis reactor. First, an industrial fixed bed reactor for ammonia production, designed by Kellogg's company, is modeled and simulated. Next, a dual-type reactor is proposed to overcome the equilibrium limitations of the exothermic ammonia synthesis reaction. The rules of similar industrial reactor design methodology and the Particle Swarm Optimization (PSO)- Differential evolution (DE) optimization method are used to obtain the reactors' best design parameters and operational conditions. The length of the reactors, the number of tubes in each reactor, the diameter of the gas-cooled reactor, and the cooling water temperature are considered decision variables for the optimization. These variables are optimized to maximize the ammonia yield. Furthermore, the effect of co-current and countercurrent flow patterns on the efficiency of the proposed reactor is investigated. A one-dimensional pseudo-heterogeneous model is applied to simulate the reactor at steady-state conditions. The governing differential equations form a boundary value problem and are solved by the shooting method. The results show that the developed dual-type reactor satisfies all the design limitations. Furthermore, this novel reactor increases the ammonia production capacity by 574 tons per day compared to the conventional Kellogg reactor.

合成氨生产是最基本的石化工艺之一。本文的重点是这一过程的核心--氨合成反应器。首先，对 Kellogg 公司设计的用于合成氨生产的工业固定床反应器进行了建模和模拟。接着，提出了一种双型反应器，以克服氨合成反应放热的平衡限制。利用类似工业反应器设计方法的规则和粒子群优化（PSO）- 差分进化（DE）优化方法，获得反应器的最佳设计参数和操作条件。反应器的长度、每个反应器中的管子数量、气冷反应器的直径和冷却水温度被视为优化的决策变量。对这些变量进行优化可使氨产量最大化。此外，还研究了同流和逆流流动模式对拟议反应器效率的影响。采用一维伪均相模型模拟稳态条件下的反应器。控制微分方程形成了一个边界值问题，并采用射流法求解。结果表明，所开发的双型反应器满足了所有设计限制。此外，与传统的 Kellogg 反应器相比，这种新型反应器每天可增加 574 吨氨的生产能力。

CoPtPd/C ternary alloys were prepared in situ as catalysts in different compositions by tuning the architecture and composition of cobalt in the reduction and displacement of ligands method to improve the efficiency of renewable energy, specifically in the methanol oxidation reaction (MOR) in alkaline medium. Chemical analyses shown that the theoretical and experimental compositions were well matched to obtain Pt₇₀Pd₁₀Co₂₀/C, Pd₇₀Pt₁₀Co₂₀/C, Co₇₀Pt₂₀Pd₁₀/C and Co₇₀Pt₁₀Pd₂₀/C ternary alloys, indicating that the method allowed precise control of components loading. Electrochemical investigations confirmed that the proposed method promoted a better synergistic effect between the components when Co is added in large amounts (70 wt%) regardless of the noble metal ratio, accelerating the oxidation of the adsorbed CO to CO₂, inhibiting the poisoning during MOR. The Co₇₀Pd₂₀Pt₁₀/C electrode materials displayed the highest electroactivity on MOR. This method is a promising alternative to reduce the amount of noble metal in catalysts used in direct alcohol fuel cells.

High-temperature proton exchange membrane fuel cells (HT-PEMFCs) are one of the key focuses in hydrogen energy research. Achieving rapid operational temperature is a critical challenge. This study combines experimental and numerical methods to investigate combined start-up strategies for HT-PEMFCs. Initially, a single-cell HT-PEMFC was constructed to obtain polarization curves. Subsequently, a three-dimensional multi-physics numerical model was developed to determine start-up times and maximum temperature differences, proposing four start-up strategies: increasing inlet gas temperature, enhancing heating plate power, combined heating without and with incorporating heat recovery. Results indicate that increasing inlet gas temperature and using a heating plate each have limitations in start-up time and membrane temperature uniformity. The optimal strategy, combining 150 °C inlet gas and a 1200 W/m² heating plate for startup, minimizes energy consumption. Additionally, incorporating heat recovery, both energy consumption and startup time can be reduced compared to scenarios without heat recovery, regardless of whether the priority is given to energy consumption or startup time.

高温质子交换膜燃料电池（HT-PEMFC）是氢能研究的重点之一。实现快速的工作温度是一项关键挑战。本研究结合实验和数值方法，对高温质子交换膜燃料电池的联合启动策略进行了研究。首先，构建了单电池 HT-PEMFC 以获得极化曲线。随后，建立了一个三维多物理场数值模型，以确定启动时间和最大温差，并提出了四种启动策略：提高入口气体温度、提高加热板功率、无热回收和有热回收的联合加热。结果表明，提高进气温度和使用加热板在启动时间和膜温度均匀性方面各有限制。最佳策略是结合 150 °C 的入口气体和 1200 W/m2 的加热板进行启动，从而最大限度地降低能耗。此外，与不使用热回收的方案相比，无论优先考虑能耗还是启动时间，使用热回收都能减少能耗和启动时间。

The mild reaction conditions, simple process, and clean raw materials make electrochemical nitrogen reduction reaction to ammonia (NRR) a promising method for producing this crucial substance for human life. The proposed catalysts have been shown to reduce the reaction barrier and improve catalytic efficiency, making them an excellent choice for this process. Carbon nanotubes coated FeMoO₄ (FeMoO₄@CNTs) nanorods are a highly efficient catalyst for fixing N₂ to NH₃. Carbon nanotubes doped FeMoO₄ improve the efficiency of electrocatalytic NRR by increasing their active surface. A superior ammonia yield of 18.49 μg h⁻¹·mg·cat⁻¹ at −0.65 V was obtained in a 0.1 mol L⁻¹ Na₂SO₄ solution, with a corresponding Faraday efficiency of 16.14%. The response of the experimental system to environmental factors was also investigated. The data clearly indicates that raising the temperature does not enhance the yield of ammonia. This reaction system is optimal for neutral or alkaline environments.

The use of hydrogen as a sustainable energy source is pushing the development of innovative sensing strategies for the monitoring of H₂ concentration during its production processes and transportation. In this work, we propose a custom quartz tuning fork (QTF) as sensor for the detection of high concentrations of hydrogen in air. The selectivity derives directly from values of molar mass and the viscosity of hydrogen molecules, significantly different from those of the other main constituents of air. Exciting the fundamental flexural mode of a commercially available 12.4 kHz-QTF, we demonstrated the linear dependence of its resonance frequency and quality factor on the H₂ concentration, passing through their relationship with molar mass and the viscosity of the H₂-air mixture. Monitoring the shift of the resonance frequency of the QTF, the H₂-component in air can be estimated with a precision level of 0.74% and accuracy error of 1.82%. The same parameters resulted 0.40% and 4.29%, respectively, when Q values are evaluated. Finally, a beat-frequency approach was proposed to speed up the acquisition in few seconds, monitoring both resonance parameters of the QTF.

氢气作为一种可持续能源的使用推动了用于监测生产过程和运输过程中氢气浓度的创新传感策略的发展。在这项工作中，我们提出了一种定制的石英音叉（QTF）传感器，用于检测空气中的高浓度氢气。其选择性直接来源于氢分子的摩尔质量和粘度值，这与空气中其他主要成分的摩尔质量和粘度值有很大不同。通过激发市售 12.4 kHz-QTF 的基本挠曲模式，我们证明了其共振频率和品质因数与氢气浓度的线性关系，以及它们与氢气混合物的摩尔质量和粘度的关系。通过监测 QTF 共振频率的偏移，可以估算出空气中的 H2 成分，精确度为 0.74%，精度误差为 1.82%。在评估 Q 值时，同样的参数分别产生了 0.40% 和 4.29% 的误差。最后，提出了一种节拍频率方法，可在几秒钟内加快采集速度，同时监测 QTF 的两个共振参数。

Residual gas trapping in porous media is a key indicator of hydrogen storage and recovery performance. The injection scheme of cushion and working gases helps maintain pressure and reduce losses. However, this information is limited in the literature. This work explores core flooding experiments (using electrical resistivity for in-situ saturation monitoring) on Bandera Grey sandstones under reservoir conditions (42 °C, 1400 psi, and 5 wt% NaCl), investigating cushion gas type and injection rate effects on storage and recovery performance. Results indicate that CO₂ injection ahead of hydrogen yielded the highest storage capacity with

S_{gi} = 0.255

, then CH₄:

S_{gi} = 0.226

and finally, N₂:

S_{gi} = 0.216

. At lower injection rates (0.2–0.6 cc/min), CH₄ cushion gas exhibited the highest recovery (42%), whereas at higher injection rates (1.2–10 cc/min), CO₂ resulted in the highest, with 33%. These findings emphasize cushion gas's role in enhancing hydrogen storage capacity and production efficiency in depleted gas reservoirs.

多孔介质中的残余气体截留是氢气存储和回收性能的一个关键指标。缓冲气体和工作气体的注入方案有助于保持压力和减少损失。然而，这方面的文献资料十分有限。这项工作在 Bandera 灰色砂岩上进行了储层条件（42 °C、1400 psi 和 5 wt% NaCl）下的岩心充注实验（使用电阻率进行原位饱和度监测），研究了缓冲气体类型和注入速度对储藏和采收性能的影响。结果表明，在注入氢气之前注入二氧化碳的储量最高，Sgi=0.255，然后是甲烷：Sgi=0.226，最后是二氧化氮：Sgi=0.216。在较低的注入率（0.2-0.6 毫升/分钟）下，CH4 缓冲气体的回收率最高（42%），而在较高的注入率（1.2-10 毫升/分钟）下，二氧化碳的回收率最高，为 33%。这些发现强调了缓冲气在提高枯竭气藏储氢能力和生产效率方面的作用。

We propose an optimization formulation for locational pricing of energy transported through a pipeline network that carries mixtures of natural gas and hydrogen from distributed sources to consumers. The objective includes the economic value provided by the pipeline to consumers of energy and suppliers of natural gas and green hydrogen, as well as incentives to lower carbon emissions by consuming the latter instead of the former. The optimization is subject to the physics of gas flow and mixing in the pipeline network as well as engineering limits. In addition to formulating this mathematical program, we synthesize the Lagrangian and derive analytical expressions for the dual variables. We propose that the dual solution can be used to derive locational marginal prices of natural gas, hydrogen, and energy, as well as the decarbonization premium paid by consumers that receive hydrogen. We derive several properties of solutions obtained using the proposed market mechanism, and demonstrate them using case studies for standard 8-node and 40-node pipeline test networks. Finally, we show that optimization-based analysis of the type proposed here is critical for making sound decisions about economic policy and infrastructure expansion for blending green hydrogen into existing natural gas pipelines.

我们提出了一种优化方案，用于对通过管道网络运输的能源进行定位定价，管道网络将天然气和氢气混合物从分布式能源输送到消费者手中。目标包括管道为能源消费者、天然气和绿色氢气供应商提供的经济价值，以及通过消费后者而不是前者来降低碳排放的激励措施。优化需要考虑管网中天然气流动和混合的物理特性以及工程限制。除了制定该数学程序外，我们还综合了拉格朗日，并推导出对偶变量的分析表达式。我们提出，二元解法可用于推导天然气、氢气和能源的地方边际价格，以及接收氢气的消费者支付的去碳化溢价。我们推导出了使用建议的市场机制获得的解决方案的若干属性，并通过对标准的 8 节点和 40 节点管道测试网络进行案例研究来证明这些属性。最后，我们表明，本文提出的这种基于优化的分析方法对于在现有天然气管道中混合绿色氢气的经济政策和基础设施扩建方面做出合理决策至关重要。

Due to its low NO_x emission index, the micromix burner technology is a promising alternative for using hydrogen in combustion. Various universities and research centers in Germany, England, and Spain have documented and studied this technology. However, the number of studies on micromix burners is limited, which hinders their implementation on an industrial scale. The present study aims to review developed works focused on micromix combustion technologies to identify the main gaps and research needs. A sample of 76 articles from 2008 was selected using the PRISMA methodology, which was categorized based on the study methodology, simulation software, and fuels used. An experimental gap has been identified in the combustion of hydrogen and methane in the selected article sample. This gap is a critical research need due to the opportunity to implement this technology in existing natural gas networks, facilitating the transition from fossil fuels to cleaner combustion processes.

由于氮氧化物排放指数低，微混合燃烧器技术是在燃烧中使用氢气的一种很有前途的替代技术。德国、英国和西班牙的多所大学和研究中心都对这项技术进行了记录和研究。然而，有关微混合燃烧器的研究数量有限，这阻碍了其在工业规模上的应用。本研究旨在回顾已发表的有关微混合燃烧技术的著作，以确定主要差距和研究需求。采用 PRISMA 方法从 2008 年选取了 76 篇文章作为样本，并根据研究方法、模拟软件和所用燃料进行了分类。在所选文章样本中发现了氢气和甲烷燃烧方面的实验空白。由于有机会在现有天然气网络中实施这项技术，从而促进从化石燃料向更清洁燃烧工艺的过渡，因此这一空白是一项关键的研究需求。
