Nitrogen-doped sp3carbon dot catalysed two-electron electrochemical oxygen reduction for efficient production of hydrogen peroxide

The nitrogen-doped DCDs electrocatalysts emerge the efficient production of hydrogen peroxide, which can achieve near 100% selectivity for the 2e − path of ORR, and the yield reached 1302.14 mmol g Catalyst −1 h −1 in the H-type electrolytic cell.
