A carbon nitride-based photocatalyst and a preparation method therefor, wherein the photocatalyst is prepared by reacting melcimide with 3,3 , ,4,4 , benzophenone tetracarboxylic dianhydride, such that the energy levels of the melcimide structure and the 3,3 , ,4,4 , benzophenone tetracarboxylic dianhydride structure may match, which may reduce the energy difference between a singlet state and a triplet state, and promote inter-system channeling. The present invention may thus be beneficial in enhancing singlet oxygen production, and improving the capability thereof for selective photocatalytic oxidation. |
