Hydrogen peroxide (H₂O₂) is an important chemical with broad applications, but its industrial production via the traditional anthraquinone method is highly energy-consuming, non-sustainable, and poses safety risks. Photocatalytic synthesis using sunlight, water, and oxygen offers an environmentally friendly alternative to realize in-situ H₂O₂ formation. However, the photocatalytic efficiency is limited by the rapid recombination of photogenerated charges. Recently, the integration of piezoelectric polarization with photocatalysis has provided an effective solution to enhance bulk charge separation and to facilitate surface catalytic process in artificial synthesis of H₂O₂. This review systematically summarizes the latest progress in piezo-photocatalytic H₂O₂ production. It firstly elaborates on the fundamental mechanisms, including principles of photocatalytic H₂O₂ production, piezoelectric effect and piezoelectric polarization, as well as the structures of different types of piezoelectric materials and the origin of their piezoelectricity. Secondly, the advances in piezoelectric field-enhanced charge dynamics and comprehensive analysis of piezoelectric field-modulated surface catalytic sites were summarized. We systematically discuss how piezoelectric polarization optimizes surface active centers, regulates intermediate adsorption/desorption, and enhances the oxygen reduction and water oxidation reactions for H₂O₂ generation. Furthermore, the applications of H₂O₂ in environmental remediation, biomedical treatments, and overall renewable energy utilization were highlighted. Finally, forward-looking perspectives on challenges and future research directions in this emerging field are provided.

过氧化氢（H2O2）是一种具有广泛应用的重要化学品，但传统的蒽醌法工业生产具有高能耗、不可持续和安全风险等特点。利用阳光、水和氧气的光催化合成提供了一种环境友好的替代方案，可以实现H2O2的原位生成。然而，光催化效率受到光生电荷快速重组的限制。近年来，压电极化与光催化的结合为增强体电荷分离和促进人工合成H2O2的表面催化过程提供了有效的解决方案。本文系统地综述了压电光催化制H2O2的最新进展。首先阐述了光催化产生H2O2的基本机理，包括光催化产生H2O2的原理，压电效应和压电极化，以及不同类型压电材料的结构和压电性的来源。其次，综述了压电场增强电荷动力学和压电场调制表面催化位点综合分析的研究进展。我们系统地讨论了压电极化如何优化表面活性中心，调节中间吸附/解吸，增强氧还原和水氧化反应以生成H2O2。重点介绍了H2O2在环境修复、生物医学治疗和可再生能源综合利用等方面的应用。最后，对这一新兴领域面临的挑战和未来的研究方向提出了前瞻性观点。

Detecting acoustic signals from high-pressure hydrogen leaks enables rapid leak identification and location, yet ambient noise often causes false or no alarms from the acoustic sensors. Thus, a joint Markov Transition Field-Support Vector Machine (MTF-SVM) analysis method is proposed to solve this issue. Firstly, two acoustic features under the Markov Transition Field are presented to construct a two-dimensional feature space. Then, a variety of high-pressure hydrogen leakage acoustic signals and ambient noise signals are measured for the training and testing of the Support Vector Machine model. Finally, this study introduces the Gaussian Kernel Function to solve the nonlinear separability problem. In addition, the Honey Badger Algorithm is introduced for determining the optimal parameters. The results show that the new model's test classification accuracy can reach 98.28 %, and the model possesses excellent robustness in a high-pressure variation range, which provides a promising method for the detection of hydrogen leaks.

检测高压氢气泄漏的声信号可以快速识别和定位泄漏，但环境噪声通常会导致声传感器发出错误警报或没有警报。为此，提出了一种联合马尔可夫过渡场-支持向量机（MTF-SVM）分析方法来解决这一问题。首先，给出马尔可夫过渡场下的两个声学特征，构建二维特征空间；然后，测量各种高压氢气泄漏声信号和环境噪声信号，对支持向量机模型进行训练和测试。最后，本文引入高斯核函数来解决非线性可分性问题。此外，还引入了蜜獾算法来确定最优参数。结果表明，新模型的测试分类准确率可达98.28%，在高压变化范围内具有良好的鲁棒性，为氢气泄漏检测提供了一种很有前景的方法。

Energy plays a pivotal role in socio-economic development, yet the burgeoning demand for conventional energy has led to significant environmental impacts and concerns over the dwindling fossil fuel stocks. In this milieu, India has witnessed significant economic growth in the past two decades with enhanced reliance on fossil fuels, increased import dependency, and a substantial greenhouse gas (GHG) footprint. In 2023, India's carbon dioxide (CO₂) emissions reached an unprecedented level of 2.9 billion metric tonnes (MT), with a 7.8 % increase from the previous year. Per capita CO₂ emissions have also increased significantly, from 0.4 to 2.07 MT during 1970–2023. The prevalent use of grey hydrogen, i.e., produced by chemical processes (e.g., coal gasification and steam methane reforming), further aggravates this environmental burden. Thus, this review explores the feasibility of biohydrogen production from renewable agricultural residues as a sustainable alternative. Our study highlights the methods, techno-economic challenges, and scope of biohydrogen production from major agro-residues (e.g., sugarcane bagasse), which can reduce GHG emissions by up to 70–90 % compared to fossil fuels, thereby addressing critical environmental issues. Overall, by systematically outlining biological and grey hydrogen production processes, the present review emphasizes the need to transition to cleaner energy sources and gives a blueprint for utilizing India's abundant agro-waste for the sustainable hydrogen economy via the microbial bioconversion process.

能源在社会经济发展中发挥着关键作用，然而，对传统能源的迅速增长的需求导致了重大的环境影响和对化石燃料库存减少的担忧。在这样的背景下，印度在过去20年里见证了显著的经济增长，对化石燃料的依赖程度提高，对进口的依赖程度提高，温室气体（GHG）排放量也大幅增加。2023年，印度的二氧化碳（CO2）排放量达到了前所未有的29亿公吨，比上一年增长了7.8%。人均二氧化碳排放量也显著增加，从1970-2023年的0.4吨增加到207吨。普遍使用灰氢，即由化学过程（例如煤气化和蒸汽甲烷重整）产生的灰氢，进一步加重了这一环境负担。因此，本综述探讨了从可再生农业残留物中生产生物氢作为可持续替代品的可行性。我们的研究强调了从主要农业残留物（如甘蔗渣）生产生物氢的方法、技术经济挑战和范围，与化石燃料相比，它可以减少高达70 - 90%的温室气体排放，从而解决关键的环境问题。总体而言，通过系统地概述生物制氢和灰制氢过程，本综述强调了向更清洁能源过渡的必要性，并给出了通过微生物生物转化过程利用印度丰富的农业废弃物实现可持续氢经济的蓝图。

This study proposes a novel hybrid combustion strategy, turbulent jet ignition coupled with spray diffusion, to enable pure methanol compression ignition in a large-bore engine, thereby overcoming methanol's low cetane number barrier. A 3D computational model was developed for a 320 mm bore engine and validated against spray and combustion experiments. The model was then employed to systematically investigate the impact of methanol injection timing. The results reveal a characteristic three-stage heat release profile, which is mechanistically linked to pre-chamber jet ignition, main-chamber flame propagation, and spray diffusion combustion. Critically, retarding injection beyond −10 °CA ATDC was found to drastically reduce the heat release rate, prolong the combustion duration, degrade combustion efficiency, and cause a sharp rise in emissions of unburned methanol, HC, CO, and formaldehyde. An optimal injection timing of −10 °CA ATDC was identified, achieving a high indicated mean effective pressure of 2.71 MPa, an indicated thermal efficiency of 46.7 %, and near-zero emissions of unburned fuel and incomplete combustion products, while maintaining NOx below IMO Tier III limits. This work demonstrates that the jet ignition-spray diffusion hybrid mode is a viable and promising pathway to high-efficiency, high-power-density, and clean-burning full-methanol compression ignition engines.

本研究提出了一种新的混合燃烧策略，即湍流射流点火与喷雾扩散相结合，从而在大缸径发动机中实现纯甲醇压缩点火，从而克服甲醇的低十六烷数障碍。建立了320 mm缸径发动机的三维计算模型，并通过喷雾和燃烧实验进行了验证。然后利用该模型系统地研究了甲醇喷射时间的影响。结果表明，该燃烧系统具有典型的三级放热特征，与预燃室喷射点火、主燃室火焰传播和喷雾扩散燃烧具有机械联系。至关重要的是，在- 10°CA ATDC以上的缓速喷射被发现会大大降低热释放率，延长燃烧持续时间，降低燃烧效率，并导致未燃烧的甲醇，HC， CO和甲醛的排放量急剧增加。确定了- 10°CA ATDC的最佳喷射时间，实现了2.71 MPa的高平均有效压力，46.7%的热效率，以及接近零的未燃烧燃料和不完全燃烧产物排放，同时将NOx保持在IMO Tier III限制以下。该研究表明，喷射点火-喷雾扩散混合模式是实现高效、高功率密度、清洁燃烧的全甲醇压缩点火发动机的可行途径。

Protonic ceramic fuel cells (PCFCs) are highly efficient energy conversion devices that operate at relatively low temperatures. Enhancing their performance strongly relies on developing cathode materials with high electrocatalytic activity. This study presents a double-doped perovskite material, Pr_1.5La_0.3Ba_0.2Ni_0.9Fe_0.1O_4+δ (PLBNF), where the electrochemical properties are significantly improved through composition and structural tuning. Comprehensive characterization confirms that the co-doping strategy effectively enhances the hydration capability, oxygen reduction reaction (ORR) activity, and operational stability. At 700 °C, the polarization resistances of the PLBNF cathode and the PLBNF-BZCYYb composite cathode are 0.11 and 0.08 Ω cm², respectively, with peak power densities reaching 1012 and 1277 mW cm⁻². Fuel cell tests demonstrate excellent operational stability for the PLBNF-BZCYYb air electrode, indicating its strong potential for application in high-performance proton-conducting ceramic fuel cells. This work provides new insights into the development of efficient fuel cell materials and advances related energy technologies.

Oxygen doping is an efficient modification strategy to enhance the solar hydrogen production performance of graphitic carbon nitride (g-C₃N₄₎. However, most current synthesis methods still rely on bottom-up approaches, while top-down synthesis strategies remain under-explored. Here, we report a novel top-down strategy for fabricating coral-like g-C₃N₄ with oxygen-bridged g-C₃N₄ (OB-CNx) through methanesulfonic acid-assisted chemical cleavage followed by secondary calcination. This method enables the precise introduction of bridging oxygen atoms while forming a unique coral-like morphology. The photocatalytic performance of OB-CNx showed enhancement over bulk g-C₃N₄, with the optimized OB-CN80 demonstrating a 6.2-fold increase in hydrogen evolution rate. Comprehensive characterization indicates that the enhancement in photocatalytic performance is attributed to electronic structure modulation induced by the introduction of the bridged oxygen atom. This modulation improves visible light absorption efficiency, narrows the bandgap, and promotes more efficient charge separation. Density functional theory (DFT) calculations further reveal that the incorporation of bridging oxygen facilitates the separation and transport of photogenerated charge carriers, thereby suppressing electron–hole recombination. This work not only provides an efficient photocatalyst but also establishes a top-down oxygen doping strategy, opening new avenues for designing advanced photocatalytic materials.

氧掺杂是提高石墨氮化碳（g-C3N4）太阳能制氢性能的有效改性策略。然而，目前大多数合成方法仍然依赖于自下而上的方法，而自上而下的合成策略仍未得到充分探索。在这里，我们报告了一种新的自上而下的策略，通过甲烷磺酸辅助化学裂解和二次煅烧，用氧桥接g-C3N4 （OB-CNx）制备类似珊瑚的g-C3N4。这种方法可以精确地引入桥接氧原子，同时形成独特的珊瑚状形态。与g-C3N4相比，OB-CNx的光催化性能有所增强，优化后的OB-CN80的析氢速率提高了6.2倍。综合表征表明，光催化性能的增强是由于引入桥接氧原子引起的电子结构调制。这种调制提高了可见光吸收效率，缩小了带隙，促进了更有效的电荷分离。密度泛函理论（DFT）计算进一步表明，桥接氧的加入促进了光生载流子的分离和输运，从而抑制了电子-空穴复合。这项工作不仅提供了一种高效的光催化剂，而且建立了自上而下的氧掺杂策略，为设计先进的光催化材料开辟了新的途径。

Dry reforming of methane (DRM), which involved converting methane and carbon dioxide into a synthesis gas, suffered from a stability issue caused by coke formation and sintering over Ni-based catalysts. In this study, a series of Ca-promoted Ni-based core–shell catalysts (4Ni-Ca_x@HSS, HSS: hollow silica spheres) were designed and synthesized using a facile one-pot microemulsion method. The optimal catalyst (4Ni-Ca_0.2@HSS) with a Ca/Ni molar ratio of 0.2 exhibited 83.3 % CH₄ and 90.2 % CO₂ conversions at 750 °C and 40,000 mL g⁻¹ h⁻¹ without coke deposition for 300 h. Studies on catalyst structure and carbon deposition indicated that Ca modification and the core–shell structure can not only promote CH₄ and CO₂ activation by reducing the size of Ni particles, thereby enhancing performance and inhibiting carbon deposition, but also enhance the interaction between Ni and SiO₂ through promoting the formation of Ni-O-Si species, so as to suppress sintering. Further validation was achieved through a combination of kinetic studies, CH₄/CO₂ temperature-programmed surface reaction experiments, and pulse tests, which collectively confirmed that the addition of Ca significantly promoted the activation of CH₄ and CO₂.

甲烷干重整（DRM）是一种将甲烷和二氧化碳转化为合成气的工艺，由于在镍基催化剂上形成焦炭和烧结，存在稳定性问题。本研究设计并合成了一系列钙促进镍基核壳催化剂（4Ni-Cax@HSS， HSS：空心硅球），采用简易的一锅微乳液法。Ca/Ni摩尔比为0.2的最佳催化剂（4Ni-Ca0.2@HSS）在750℃、40000 mL g−1 h−1条件下，无积炭300 h， CH4转化率为83.3%，CO2转化率为90.2%。对催化剂结构和碳沉积的研究表明，Ca改性和核壳结构不仅可以通过减小Ni颗粒的尺寸来促进CH4和CO2的活化，从而提高性能，抑制碳沉积；还通过促进Ni- o - si物质的形成，增强Ni与SiO2之间的相互作用，从而抑制烧结。通过动力学研究、CH4/CO2温控表面反应实验和脉冲实验进一步验证，共同证实Ca的加入显著促进了CH4和CO2的活化。

Using hydrogen is an essential step for decarbonisation. However, the detection of H₂ concentration in gas mixtures with GC-TCD can be complicated, especially with He as the carrier gas. In the article, Fused Silica-PLOT columns were used for H₂ detection with different detector temperatures and sample volumes, examining the response signal of peak height and area.

Peak reversal was not observed with 50 μl, but at 200 μl and 250 °C, the entire concentration range for the M peak, and 70–100 vol% H₂ for the U peak could be selected. Using 110 °C and 1000 μl sample, 0.07 vol% hydrogen could be detected, lower than the detectable values described in the literature.

Although the manuscript focuses on the evolution of the hydrogen response signal, the presented method is multi-purpose and suitable for various hydrogen-containing gaseous fuels. Such a detailed description could help understanding the behaviour of H₂ – He mixtures.

使用氢是脱碳的必要步骤。然而，用GC-TCD检测混合气体中H2的浓度比较复杂，特别是以He为载气时。本文采用熔融硅柱（Fused Silica-PLOT）在不同的检测器温度和样品体积下进行H2检测，检测峰高和面积的响应信号。当浓度为50 μl时，未观察到峰反转，但在200 μl和250°C时，M峰可以选择整个浓度范围，U峰可以选择70-100 vol% H2。在110℃和1000 μl样品条件下，可检出0.07 vol%的氢，低于文献中描述的检出值。虽然手稿的重点是氢响应信号的演变，但所提出的方法是多用途的，适用于各种含氢气体燃料。这种详细的描述有助于理解H2 - He混合物的行为。

Microgrids are an effective means to manage electricity flows between diverse renewable electricity sources, energy storage and loads. Hydrogen offers a promising solution for sustainable decarbonisation in sectors of the energy economy where electrification alone will not suffice. When hydrogen is integrated into a microgrid as a second energy vector, the advantages of DC microgrids become significant, fundamentally because renewable energy components such as solar photovoltaics, batteries, electrolysers and fuel cells are “DC-inside”, and asynchronous machines such as wind turbines are effectively so. The paper focuses on bridging the gap between the presently disparate fields of hydrogen energy and DC power management, addressing topics of practical importance in the process to envision and design a DC hydrogen microgrid, from key concepts through to the practicalities of hydrogen storage. Opportunities for deployment of DC hydrogen microgrids on islands, in regions with uncertain electricity supply, for offshore industries, at ports, for mining and for processing “green” metals needed for decarbonisation are discussed, along with challenges and barriers. Presently, patchy supply chains and capital cost are significant problems for commercial projects. Demonstration projects can help to develop a strong knowledge base, paving the way for the implementation of DC hydrogen microgrids at scale in diverse applications and contributing to a decarbonised future.

微电网是管理不同可再生电力来源、储能和负荷之间的电力流动的有效手段。氢为能源经济领域的可持续脱碳提供了一个有希望的解决方案，在这些领域，仅靠电气化是不够的。当氢作为第二能量载体被整合到微电网中时，直流微电网的优势变得显著，从根本上说，因为可再生能源组件，如太阳能光伏、电池、电解槽和燃料电池都是“直流内部”，而风力涡轮机等异步机器实际上也是如此。本文的重点是弥合目前不同领域的氢能源和直流电源管理之间的差距，解决在设想和设计直流氢微电网过程中具有实际重要性的主题，从关键概念到储氢的实用性。讨论了在岛屿、电力供应不确定地区、海上工业、港口、采矿和加工脱碳所需的“绿色”金属方面部署直流氢微电网的机会，以及挑战和障碍。目前，商业项目面临的主要问题是供应链不完整和资金成本问题。示范项目可以帮助建立强大的知识基础，为在各种应用中大规模实施直流氢微电网铺平道路，并为脱碳的未来做出贡献。
