In this work, structure-deficient mesoporous g-C3N4 (DMCN) was fabricated via a facile hard template approach with water-bath aging pretreatment. The in situ introduced cyano groups (–C≡N) and hydroxyl groups (–OH) effectively modulated the energy levels, improved visible light absorption, and meanw...
