Abstract

Cu2O photocatalyst is synthesized by solvothermal method. Morphology and structure of Cu2O photocatalyst are analyzed by SEM, XRD and N2 sorption technique. The catalytic performances and reaction kinetics of Cu2O photocatalyst for the degradation of methylene blue (MB) are investigated. The toxicity effect of Cu2O photocatalyst on yeast Saccharomyces cerevisiae is also studied. The results show pure Cu2O photocatalyst with truncated octahedron morphology is obtained and demonstrates good potential on degradation of MB. The degree of MB degradation is improved significantly in the presence of H2O2, and the optimum H2O2 concentration is 1.3 wt%. The degradation rate constant decreases as the initial MB concentration increases, and the degradation reaction can be represented by pseudo-first-order kinetics model. Cu2O photocatalyst shows a good reusability and slight limited growth rate of Saccharomyces cerevisiae, suggesting it can serve as an effective and recyclable photocatalyst.
