Summary:Hydrogen peroxide (H 2 O 2 ) is a versatile and environmentally friendly oxidant with a wide range of industrial and household applications. In recent years, the decentralization of H 2 O 2 production through the two-electron oxygen reduction reaction (ORR) has emerged as an attractive alternative to the well-established anthraquinone process. And of the many electrocatalysts developed for the two-electron ORR to produce H 2 O 2 , metal-free carbon catalysts (MFCCs) have received extensive attention due to their cost-effectiveness and natural abundance. Based on this, this review will provide an in-depth overview into MFCC design and fabrication with an emphasis on porosity control, heteroatom doping, oxygen functionalization, defect engineering and organic-inorganic interface engineering. This review will also discuss and analyze the interplays between these factors in terms of MFCC catalytic activity and selectivity towards H 2 O 2 production. Furthermore, major technical challenges are presented, and future research directions are proposed to guide further development towards practical application. Recent progress in the development of metal-free carbon catalysts for ORR to H 2 O 2 .
