Enhanced photocatalytic H2O2 yield by single-atom Pt decorated carbon nitride sheets via boosting *OOH intermediate generation

Pt-SA/g-C 3 N 4 achieves an H 2 O 2 yield of 836 μmol L −1 h −1 under visible light. Single-atom Pt promotes charge separation. In situ SERS directly observed OOH formation. DFT calculations indicate Pt inhibits OOH cleavage, enhancing H 2 O 2 production.
