摘　　要：过氧化氢(H_(2)O_(2))的传统合成方法存在能耗高、安全隐患大等问题。光催化合成H_(2)O_(2)具有安全、环保和节能等优势,符合可持续发展要求,极具发展潜力。共轭聚合物作为典型的光催化材料,通过结构改性提升其光催化性能已成为解决该问题的一个途径。基于光催化合成H_(2)O_(2)的机理,综述了共轭聚合物改性策略在光催化领域的研究进展,重点分析了表面改性、供体-受体结构构建、异质结体系构筑、催化位点调控等改性策略对光催化合成H_(2)O_(2)性能的影响。鉴于共轭聚合物存在电子-空穴对易复合问题,提出优化H_(2)O_(2)生成途径及开发气-液-固三相光催化体系是未来共轭聚合物光催化生成H_(2)O_(2)的主要研究方向,为设计出高效、绿色、稳定的光催化剂提供新思路。Traditional synthesis methods of hydrogen peroxide(H_(2)O_(2))have problems such as high energy consumption and safety hazards.Photocatalytic synthesis of H_(2)O_(2) has the advantages of being safe,environment-friendly and energy efficient,meeting the requirements of sustainable development,and showing great development potential.As typical photocatalytic materials,conjugated polymers have become an approach to solving these problems by enhancing their photocatalytic properties through structural modification.Based on the mechanism of photocatalytic synthesis of H_(2)O_(2),this review summarizes the research progress in modification strategies of conjugated polymers in the field of photocatalysis,focusing on the effects of surface modification,donor-acceptor structure construction,heterojunction system construction,and catalytic site regulation on the performance of photocatalytic synthesis of H_(2)O_(2).Given that conjugated polymers are prone to electron-hole pair recombination,optimizing H_(2)O_(2) generation pathway and developing gas-liquid-solid three-phase photocatalytic system are proposed as the main research directions for photocatalytic H_(2)O_(2) generation with conjugated polymers in the future,providing new ideas for designing efficient,green and stable photocatalysts.
