Abstract

Photocatalytic hydrogen peroxide (H2O2) synthesis, driven by solar energy, offers a sustainable and cleaner alternative for producing green H2O2 from water and oxygen. 2D photocatalysts have emerged as powerful materials for this purpose due to their unique physiochemical properties such as a flexible planar structure and large surface area. This review provides a comprehensive overview of the latest advances in 2D photocatalytic materials employed in H2O2 synthesis, including metal oxides, metal chalcogenides, bismuth-based materials, graphitic carbon nitrides (g-C3N4), metal−organic frameworks (MOFs), and covalent organic frameworks (COFs). Beginning with an extensive introduction to possible reaction routes for photocatalytic H2O2 synthesis, we summarize the common methods for H2O2 detection, crucial for obtaining reliable results in H2O2 studies. Additionally, we highlight molecular-level modification strategies for 2D photocatalysts, such as surface modification, ion doping, defect engineering, and heterojunction construction, which promote high-efficiency solar-to-chemical conversion for sustainable H2O2 photosynthesis. Furthermore, we discuss key issues and provide perspective outlooks for the efficient and sustainable generation of H2O2 in scale-up industrial production. This review offers in-depth insights into different reaction pathways of H2O2 synthesis and provides design principles for 2D photocatalysts to enhance H2O2 production, guiding the development of efficient photocatalysts for H2O2 synthesis.

用于合成过氧化氢的二维光催化剂
由太阳能驱动的光催化过氧化氢(H2O2)合成为利用水和氧气生产绿色 H2O2 提供了一种可持续的清洁替代方法。二维光催化剂因其独特的理化特性,如灵活的平面结构和大表面积,已成为实现这一目的的有力材料。本综述全面概述了用于 H2O2 合成的二维光催化材料的最新进展,包括金属氧化物、金属瑀、铋基材料、石墨化碳氮化物 (g-C3N4)、金属有机框架 (MOF) 和共价有机框架 (COF)。从广泛介绍光催化 H2O2 合成的可能反应路线开始,我们总结了 H2O2 检测的常用方法,这些方法对于获得 H2O2 研究的可靠结果至关重要。此外,我们还重点介绍了二维光催化剂的分子级改性策略,如表面改性、离子掺杂、缺陷工程和异质结构建,这些策略可促进高效的太阳能-化学转化,从而实现可持续的 H2O2 光合作用。此外,我们还讨论了在规模化工业生产中高效、可持续生成 H2O2 的关键问题,并提供了前景展望。本综述深入探讨了 H2O2 合成的不同反应途径,并提供了二维光催化剂提高 H2O2 产能的设计原则,为开发用于 H2O2 合成的高效光催化剂提供了指导。
