Abstract

Abstract: The structural, electronic, and optical properties of two-dimensional (2D) CdO/g-C6 N6 nanocomposite are studied through hybrid density functional. The results show that the CdO monolayer can contact with g-C6 N6 through van der Waals interaction to form the CdO/g-C6 N6 heterostructure. A narrower bandgap value is found for CdO/g-C6 N6, compared to both CdO monolayer and g-C6 N6 monolayer, which is conductive to the absorption of visible-light. Furthermore, the CdO/g-C6 N6 composite shows appropriate band alignment and efficient charge separation. These factors indicate that the CdO/g-C6 N6 composite is a promising visible-light water-splitting photocatalyst.
