过氧化氢是一种重要的化学品，引起了能源和环境应用的强烈关注。然而，不断增长的市场需求与传统蒽醌方法的不可持续性之间的斗争促使人们探索替代的H ₂ O ₂生产工艺。尽管已经提出了几种新的生产工艺，但环保型太阳能驱动的H ₂ O ₂生产最受关注，因为它只需要水、氧气和光能的输入。功能性光响应催化剂的合理设计促进H ₂ O ₂光催化和光电催化方法的生产。一般来说，这些是通过促进 OOH*/OH*/O* 关键中间体的优先吸附、增强光吸收、促进电荷分离以及以选择性数量的相关电荷加速表面电荷转移来实现的。该综述系统地总结了光（电）催化剂处理 H ₂ O _2的策略通过水氧化和氧还原途径生产。尽管氧还原路线被认为在社区中更受欢迎，但选择性水氧化正在成为一种令人信服的替代方案。此外，还深入讨论了流行的假设、最先进的催化剂、关键挑战和观点。本综述旨在增强对该研究领域的理解并提高对可持续 H ₂ O ₂生产的兴趣。

Clean Production of Hydrogen Peroxide: A Heterogeneous Solar-Driven Redox Process

Hydrogen peroxide is an essential chemical that is attracting strong attention for energy and environmental applications. However, the struggle between the growing market demand and the unsustainability of the conventional anthraquinone method motivates the exploration of alternative H₂O₂ production processes. Although several new production processes have been proposed, the environmental-friendly solar-driven H₂O₂ production attracts most attention because of the only inputs of water, oxygen, and light energy. The rational design of functional photo-responsive catalysts promotes H₂O₂ production in the photocatalytic and photoelectrocatalytic approaches. These are, in general, achieved by facilitating the preferential adsorption of key intermediates of OOH*/OH*/O*, enhancing the light absorption, promoting the charge separation, and accelerating the surface charge transfer with selective number of involved charges. This review systematically summarizes strategies for photo(electro)catalysts toward H₂O₂ production via both the water oxidation and oxygen reduction pathways. Though the oxygen reduction route is perceived as more popular in the community, selective water oxidation is emerging as a convincing alternative. Furthermore, prevailing hypotheses, state-of-the-art catalysts, critical challenges, and perspectives are discussed in depth. This review aims to enhance the comprehension of this research field and promote interest in sustainable H₂O₂ production.
