摘要：
Various morphologies of Cu2O thin films were prepared on indium tin oxide (ITO) conducting glass using electrodeposition approach with diverse addictive agents. The obtained samples were characterized by XPS, XRD, SEM and UV-Vis spectroscopy to study the microstructure, morphology and optical properties of the films, respectively. The degradation of methylene blue over different morphologies of Cu2O thin films was evaluated in H2O2-Cu2O system. The results indicate that the as-prepared Cu2O micrometer crystals are of high-purity. More than 92.1 % of methylene blue can be degraded in 3 h by Cu2O. Recycling results reveal that more than 92.4% of methylene blue can be decomposed within 8 cycles. And the degradation rate could still reach 82.4% after 11 cycles.
