摘要

Visible light Fenton method, a new technology for solving water pollution, has attracted much attention due to its advantages of high efficiency, good stability, easy operation, and visible light absorption. In this study, CuO/Cu2O/ZnO composites Fenton catalyst were prepared by anodic oxidation method and hydrothermal method on the base of copper foam. The microstructure, composition and optical properties of the samples were systemically characterized by XRD, XPS, SEM, TEM and UV-Vis measurements. The visible-light Fenton catalytic performance of the samples was evaluated by the degradation of Rhodamine B (RhB) under visible light. The research results indicate that compared with the base CuO/Cu2O nanoarrays, the photocatalytic degradation performance of CuO/Cu2O/ZnO composites are improved. The degradation rate of 98% RhB solution was 0.18 min−1, which was 1.5 times of CuO/Cu2O-60 nanoarray. After five cycles, the degradation rate of RhB solution was 93% in 30 minutes. ZnO and CuO/Cu2O nanoarrays formed heterojunction, which improved the visible light absorption, inhibited the recombination efficiency of photogenerated electrons and holes, and effectively improved the catalytic degradation performance of visible light Fenton.
