• We investigate the photogenerated electron kinetics of a thermal-decomposed polymeric carbon nitride (TCN) synthesized in air using femtosecond time-resolved diffuse reflectance spectroscopy. We find that the oxygen functional groups in TCN contribute to the formation of reactive shallow trap states for photogenerated electrons, leading to an enhanced activity for photocatalytic hydrogen evolution. Oxygen functional group-introduced shallow electron trap states enhance the photocatalytic activity of the thermal-decomposed polymeric carbon nitride for hydrogen evolution.
