Abstract
Abstract Electrochemical synthesis of hydrogen peroxide (H 2 O 2 ) provides a clean and safe technology for large-scale H 2 O 2 production. The core of this project is the development of highly active and highly selective catalysts. Recent studies demonstrate that carbonaceous materials are favorable catalysts because of their low-cost and tunable surface structures. This brief review first summarizes the strategies of carbonaceous material engineering for selective two-electron O 2 reduction reaction and discusses potential mechanisms. In addition, several device designs using carbonaceous materials as catalysts for H 2 O 2 production are introduced. Finally, research directions are proposed for practical application and performance improvement.
