Effect of Copper-Modification of g-C₃N₄ on the Visible-Light-Driven Photocatalytic Oxidation of Nitrophenols.

ABSTRACT: Graphitic carbon nitride (g-C₃N₄) has proved to be a promising heterogeneous photocatalyst in the visible range. It can be used, among others, for the oxidative conversion of environmentally harmful nitrophenols occurring in wastewater. However, its photocatalytic activity needs to be enhanced, which can be achieved by modification with various dopants. In our work, copper-modified g-C₃N₄ was prepared by ultrasonic impregnation of the pristine g-C₃N₄ synthesized from thiourea. The morphology, microstructure, and optical properties of the photocatalysts were characterized by XRD, FT-IR, DRS, SEM, XPS, and TEM. DRS analysis indicated a slight change in both the CB and the VB energies of Cu/g-C₃N₄ compared
