Abstract: Hydrogen peroxide (H2O2) has been recognized as a rather important chemical with extensive applications in environmental protection, chemical synthesis, military manufacturing, etc. However, the mature industrial strategy (i.e., anthraquinone oxidation) for H2O2 production is featured with heavy pollution and high energy consumption. Photocatalytic technology has been regarded as a sustainable strategy to convert H2O and O2 into H2O2. Recently, porous organic framework materials (POFs) including metal-organic frameworks (MOFs), covalent organic frameworks (COFs), covalent triazine frameworks (CTFs), covalent heptazine frameworks (CHFs), and hydrogen-bonded organic frameworks (HOFs) have exhibited significant potential for green H2O2 photosynthesis by virtue of their diverse synthesis methods, enormous specific surface areas, flexible design, adjustable band structure, and photoelectric property. In this review, the recent advances in H2O2 photosynthesis based on POFs are comprehensively investigated. The modification strategies to improve H2O2 production and their photocatalytic mechanisms are systematically analyzed. The current challenges and future perspectives in this field are highlighted as well. This review aims to give a complete picture of the research effort made to provide a deep understanding of the structure-activity relationship of H2O2 photogeneration over POFs, thus inspiring some new ideas to tackle the challenges in this field, and finally stimulating the efficient development of organic semiconductors for sustainable photogeneration of H2O2.
