开发碳基材料催化氧还原反应（ORR）的两电子（2e−）途径为过氧化氢（H2O2）的生产提供了巨大的潜力。石墨烯及其衍生物作为一类新型的二维碳材料，由于其独特的结构、物理和化学性质，在2e ORR中作为优良的无贵金属催化剂受到越来越多的关注。本文综述了石墨烯家族主要成员的合成方法、石墨烯基电极及其在电化学体系中H2O2生成中的应用。阐述了石墨烯家族在电化学体系中的功能，如加速电子传递和增加阴极氧传递等，旨在揭示石墨烯及其衍生物促进H2O2生成的机理。最后，展望了石墨烯家族作为H2O2催化剂的应用前景。
The development of carbon-based materials to catalyze two-electron (2e−) pathway of oxygen reduction reaction (ORR) offers great potential for hydrogen peroxide (H2O2) production. As a class of novel two-dimensional (2D) carbon materials, graphene and its derivatives have raised increasing attention as excellent noble-metal-free catalysts in 2e ORR due to their unique structure, physical and chemical properties. This review focuses on the synthesis of main graphene family members and graphene based electrodes, as well as their applications for H2O2generation in electrochemical systems. We describe the functions of the graphene family in electrochemical systems, such as accelerating electron transfer and increasing oxygen transfer for cathodes in electrochemical systems, aiming to reveal the enhancement mechanisms of graphene and its derivatives on H2O2production. Furthermore, the challenges and prospects for graphene family used as catalyst for H2O2production in the future are also proposed.
