Toward More Efficient Carbon-Based Electrocatalysts for Hydrogen Peroxide Synthesis: Roles of Cobalt and Carbon Defects in Two-Electron ORR Catalysis

Yuanjie Zheng et al.

Summary: Electrochemical production of H2O2 is an eco-friendly and cost-effective method. Metal-doped carbon-based catalysts are commonly used for 2e-ORR due to their high selectivity. The role of metals and carbon defects in H2O2 production is still unclear. This study obtained a Co-N/O-C catalyst with a Faradaic efficiency greater than 90% in alkaline electrolyte by varying the Co loading in the pyrolysis precursor. Detailed studies revealed that carbon atoms in C-O-C groups at defect sites were the active sites for 2e-ORR in the Co-N/O-C catalysts. The direct contribution of cobalt single atom sites and metallic Co for the 2e-ORR performance was negligible, but Co played an important role in the pyrolytic synthesis of the catalyst.
