Abstract

Photocatalytic technology harnesses solar energy to facilitate chemical transformations, presenting significant potential in energy generation and environmental remediation. However, the conventional O₂ evolution process is hindered by high reaction barriers and inefficiencies, which limit its widespread application. Therefore, exploring novel photocatalytic coupling strategies to replace water oxidation has become a key route to enhance the efficiency of H₂ production. In this review, organic pollutants removal and the valorization of organics as substitutes for water oxidation coupling strategies for photocatalytic H₂ production are comprehensively summarized. These strategies not only circumvent the high reaction barriers associated with O₂ evolution to enhance the H₂ production but also aid in the removing of organic pollutants or synthesis of value-added chemicals. We also present future research directions and underscore the significance of advanced catalyst design, in-depth analysis of reaction mechanisms, and systematic optimization strategies in realizing an efficient and sustainable photocatalytic process. This guidance is anticipated to provide theoretical and practical new insights for the future development of photocatalytic coupling reactions, fostering further explorations in the realm of renewable energy and environmental governance.

用于制氢的创新光催化耦合战略的先进开发

光催化技术利用太阳能促进化学转化，在能源生产和环境修复方面具有巨大潜力。然而，传统的氧气进化过程受到高反应障碍和低效率的阻碍，限制了其广泛应用。因此，探索新型光催化耦合策略以取代水氧化已成为提高 H2 生产效率的关键途径。本综述全面总结了光催化制取 H2 的有机污染物去除和有机物价值化替代水氧化耦合策略。这些策略不仅规避了与氧气进化相关的高反应障碍，提高了 H2 产率，还有助于去除有机污染物或合成高附加值化学品。我们还介绍了未来的研究方向，并强调了先进催化剂设计、深入分析反应机理和系统优化策略对于实现高效、可持续光催化过程的重要意义。本指南有望为光催化偶联反应的未来发展提供理论和实践方面的新见解，促进可再生能源和环境治理领域的进一步探索。
