Figure 1. Principles of photocatalytic water splitting reaction & CO2RR (i) the process of photo-excitation to generate photogenerated electrons and holes, (ii) separation and migration of photogenerated charges; (ii’) bulk recombination of photogenerated charges; (ii’’) surface recombination of photogenerated charges; (iii) O2 evolution reaction (OER); (iii’) H2 evolution reaction (HER); (iii’’) CO2RR.
