Efficient solar-driven hydrogen peroxide production enabled by a perovskite electrochemical device integrated with a cobalt-based chiral catalyst

Efficient H 2 O 2 production was achieved on chiral Co NH catalyst, enhancing 2e − ORR by removing oxygen intermediate. A Co NH decorated perovskite cathode showed −18 mA cm −2 at 1.2 V RHE , and when paired with an IOR catalyst, delivered 9.4% SCC.
