Constructing Interfacial Boron‐Nitrogen Moieties in Turbostratic Carbon for Electrochemical Hydrogen Peroxide Production

Electrochemical oxygen reduction reaction (ORR) provides a green route for decentralized H2O2 synthesis, where astructure-selectivity relationship is pivotal the control of highly selective and active two-electron pathway. Here, we report fabrication boron nitrogen co-doped turbostratic carbon catalyst with tunable B-N-C configurations (CNB-ZIL) by assistance zwitterionic liquid (ZIL) electrochemical hydrogen peroxide production. Combined spectroscopic analysis reveals fine tailored B-N moiety in CNB-ZIL, interfacial species homogeneous distribution tend to segregate into hexagonal nitride domains at higher pyrolysis temperatures. Based on experimental observations, correlation between moieties HO2- selectivity established. The CNB-ZIL electrocatalysts optimal exhibit high small overpotentials alkaline media, giving yield ~1787 mmol gcatalyst-1 h-1 -1.4 V flow-cell reactor.
