Interfacial polarization of boron carbon nitride gates nickel sites toward selective two-electron oxygen reduction.
Selective electrosynthesis of hydrogen peroxide (H2O2) via the two-electron oxygen reduction reaction (2e- ORR) requires a delicate balance between O2 activation and the suppression of OO bond cleavage in the *OOH intermediate. Here, a polarization-gated metal-BCN interface to direct ORR toward selective H2O2 productio...
