ABSTRACT
It is of great significance to regulate the coordination environment ZrO2 enhance its photocatalytic hydrogen evolution activity. In this paper, non-metallic elements (A = C, N, P, S) doped photocatalysts are designed based on first-principles, and further loaded with single-atom Pt. The relationship between composition performance during doping loading explained through electronic properties, their explored. Loading have a synergistic effect modification ZrO2, effectively improves catalytic performance. Among them, P greatly reduces Gibbs free energy reaction. After introduction Pt single atoms, [email protected]2(1 1 1)-P still has best structure for evolution, good surface activity significantly reaction(HER) (free −0.01 eV). This design provides new model system also some ideas understanding effects doping.
