The development of carbon-based materials to catalyze two-electron (2e) pathway of oxygen reduction reaction (ORR) offers great potential for hydrogen peroxide (HO) 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 HO generation 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 HO production. Furthermore, the challenges and prospects for graphene family used as catalyst for HO production in the future are also proposed.
