Hydrogen peroxide (H₂O₂) has exhibited huge application value in many fields including chemical synthesis, medicine, environmental remediation, and fuel cells. Traditional anthraquinone method for H₂O₂ commercial production has emerged the drawbacks of toxicity, H₂ consumption and high energy input. Photocatalytic production of H₂O₂, which only requires water, oxygen, solar light and catalyst, is a novel and green technique, and potentially becomes one of the substitutes for anthraquinone method. Herein, we comprehensively review the research progress in the reported semiconductor catalysts, their modification strategies, as well as the related photocatalysis systems and mechanisms for the light driven H₂O₂ production. In detail, the photocatalysts are introduced from different families including ZnO, g-C₃N₄, TiO₂, metal complexes, metal sulfides, Bi containing semiconductors, and carbon materials. In the meantime, their modification strategies are systematically evaluated aiming at the improvement in the structures and the photoelectrical properties of semiconductors, as well as their effective activation of molecular O₂, and inhibition of H₂O₂ decomposition. Finally, this review is concluded with a brief summary and outlook, and the major challenges for the development of photocatalytic H₂O₂ production over the emerging semiconductor photocatalysts.

过氧化氢（H ₂ O ₂）在化学合成，医学，环境修复和燃料电池等许多领域均显示出巨大的应用价值。传统的蒽醌商业化生产H ₂ O _2的方法已经出现了毒性，H ₂消耗和高能量输入的缺点。H ₂ O _2的光催化生产它仅需水，氧气，太阳光和催化剂，是一种新颖的绿色技术，有可能成为蒽醌法的替代品之一。在本文中，我们全面回顾了报道的半导体催化剂的研究进展，其改性策略以及光驱H ₂ O ₂生产的相关光催化体系和机理。详细地，从包括ZnO，gC ₃ N ₄，TiO ₂在内的不同族引入光催化剂。，金属络合物，金属硫化物，含Bi的半导体和碳材料。同时，针对半导体的结构和光电性能的改进，以及它们对分子O ₂的有效活化和对H ₂ O ₂分解的抑制作用，对它们的修饰策略进行了系统评价。最后，本综述以简短的总结和展望以及在新兴的半导体光催化剂上发展光催化H ₂ O ₂生产的主要挑战作了总结。
