Identifying Activity and Selectivity Trends for the Electrosynthesis of Hydrogen Peroxide via Oxygen Reduction on Nickel–Nitrogen–Carbon Catalysts

The electrocatalytic production of hydrogen peroxide (H2O2) through the two-electron oxygen reduction reaction (ORR) requires cost-effective catalysts with high selectivity, activity, and stability. Herein we report the synthesis and electrocatalytic assessment of nickel–nitrogen–carbon (Ni–N–C) electrocatalysts to gain insight into ORR activity and selectivity toward the production of H2O2. The activity and selectivity of the catalysts …
