摘　　要：过氧化氢(H_(2)O_(2))是一种绿色强效氧化剂,能够在温和条件下氧化液体介质中的多种有机和无机基质,与化学计量氧化剂相比,其活性氧含量高,且只释放H_(2)O和O_(2)作为最终产物,具有环保高效的独特优势。相对于传统的蒽醌产H_(2)O_(2)工艺,光催化过程具有低耗、环保、安全等的优势。无金属光催化剂由于其合成简单、成本低、环境友好、生物相容性高等的特征成为光催化产H_(2)O_(2)的理想光催化剂之一。文章论述了无金属光催化剂近年来在光催化产H_(2)O_(2)领域最新进展。主要包括:光催化产H_(2)O_(2)的基本机理及过程以及石墨氮化碳(g-C_(3)N_(4))、共价有机框架(COFs)、有机聚合物主要无金属光催化剂的特征及其在光催化产H_(2)O_(2)重要进展。讨论了现阶段光催化产H_(2)O_(2)研究中遇到的问题和挑战,并提出一些见解和方法,特别是在光催化产H_(2)O_(2)机理过程、催化剂稳定性和H_(2)O_(2)分离、光催化产H_(2)O_(2)速率提升方面。该综述旨在促进光催化产H_(2)O_(2)的发展及应用。Hydrogen peroxide(H_(2)O_(2))is a green and powerful oxidant that can oxidize various organic and inorganic matrices in liquid media under mild conditions.Compared with stoichiometric oxidants,it has a high active oxygen content and only releases H_(2)O and O_(2)as the final products,which has the unique advantage of environmental protection and efficiency.Compared with the traditional anthraquinone H_(2)O_(2)production process,the photocatalytic process has advantages such as low consumption,environmental protection,and safety.Metal-free photocatalysts have became one of the ideal photocatalysts for photocatalytic production of H_(2)O_(2)due to their simple synthesis,low costs,environmental friendliness,and high biocompatibility.This paper reviews the latest progress of metal-free photocatalysts in the field of photocatalytic H_(2)O_(2)production in recent years.It mainly includes the basic mechanism and process of photocatalytic H_(2)O_(2)production,as well as the characteristics of major metal-free photocatalysts such as graphitic carbon nitride(g-C_(3)N_(4)),covalent organic frameworks(COFs),organic polymers and their important progress in photocatalytic H_(2)O_(2)production.In addition,we also discussed the problems and challenges encountered in the research of photocatalytic H_(2)O_(2)production at this stage,and put forward some insights and methods.Especially in the process of photocatalytic H_(2)O_(2)production mechanism,catalyst stability and H_(2)O_(2)separation,and photocatalytic H_(2)O_(2)production rate increase.This review aims to promote the development and application of photocatalytic production of H_(2)O_(2).
