Abstract

Dual-channel redox reaction system is advantageous for photocatalytic hydrogen (H₂) production when coupled with photoreforming oxidation of waste materials, benefiting both thermodynamically and kinetically. However, existing reviews primarily focus on specific oxidation reactions, such as oxidative organic synthesis and water remediation, often neglecting recent advancements in plastic upgrading, biomass conversion, and H₂O₂ production, and failing to provide an in-depth discussion of catalytic mechanisms. This review addresses these gaps by offering a comprehensive overview of recent advancements in dual-channel redox reactions for photocatalytic H₂-evolution and waste photoreforming. It highlights waste-to-wealth design concepts, examines the challenges, advantages and diverse applications of dual-channel photocatalytic reactions, including photoreforming of biomass, alcohol, amine, plastic waste, organic pollutants, and H₂O₂ production. Emphasizing improvement strategies and exploration of catalytic mechanisms, it includes advanced in-situ characterization, spin capture experiments, and DFT calculations. By identifying challenges and future directions in this field, this review provides valuable insights for designing innovative dual-channel photocatalytic systems.

双通道氧化还原反应，用于光催化 H2 进化和废料的光转化氧化

双通道氧化还原反应系统在光催化制氢（H2）过程中与废料的光形成氧化反应相结合，在热力学和动力学方面都具有优势。然而，现有的综述主要关注特定的氧化反应，如氧化有机合成和水修复，往往忽视了塑料升级、生物质转化和 H2O2 生产方面的最新进展，也没有对催化机理进行深入讨论。本综述针对这些不足，全面概述了用于光催化 H2 进化和废物光转化的双通道氧化还原反应的最新进展。文章重点介绍了变废为宝的设计理念，探讨了双通道光催化反应的挑战、优势和各种应用，包括生物质、酒精、胺、塑料废物、有机污染物的光转化和 H2O2 生产。该书强调改进策略和催化机理探索，包括先进的原位表征、自旋捕获实验和 DFT 计算。通过确定该领域的挑战和未来方向，本综述为设计创新的双通道光催化系统提供了宝贵的见解。
