a Photocatalytic H2O2 yield of CN-KI3-KI-MV in the presence of different saturated gases and scavengers. The error bars represent the standard deviation of three replicate tests. b EPR spectra of CN, CN-KI, CN-KI3-KI, and CN-KI3-KI-MV under dark and visible light conditions. c H2O2 and •O2− yields in CN-MV, CN-KI-MV, and CN-KI3-KI-MV systems. d, e, f DRIFTS spectra of CN-KI3-KI-MV under different reaction conditions.
