Abstract

Electrochemical oxygen reduction for producing clean hydrogen peroxide (H2O2) is a promising alternative approach to the industrial anthraquinone method. At present, the most pressing challenge is the development of oxygen reduction electrocatalysts with sufficient activity, stability, and 2e pathway selectivity. Here, the electrocatalytic properties of a series of graphitic carbon nitride (g-C3N4) catalysts with different concentrations of nitrogen species (C-N-C and N-(C)3) are explored for H2O2 production. Electrochemical studies show that the selectivity of g-C3N4 for hydrogen peroxide generation in alkaline electrolytes reaches ≈90%. To explain the observed results, the structure, composition, and physical and chemical properties of g-C3N4 catalysts synthesized from different precursors are compared with their electrocatalytic performance. This research contributes to the discovery and design of a high-performance nitrogen-doped carbon catalysts for the production of hydrogen peroxide.
