摘要: 在Cu基底上制备Cu（OH）2，水热条件下KMnO4在Cu（OH）2表面分解为MnO2、煅烧得到Cu-CuO-MnO2核壳催化剂。用XRD、SEM、Raman和TG对该催化剂进行了表征，并研究了其催化H2O2降解亚甲基蓝的性能。研究了催化剂制备过程中KMnO4分解反应时间、煅烧温度及催化过程中H2O2的用量对其催化降解性能的影响。结果表明：KMnO4分解反应时间3 h、煅烧温度250℃、H2O2的用量6 mL时，该催化剂的使用可使亚甲基蓝降解率达到96.4%。催化剂的重复循环使用结果表明，循环5次使用降解率均高于94%。表明Cu-CuO-MnO2核壳催化剂具有较高的催化性能及稳定性，对染料废水的处理具有潜在应用价值。

Abstract: Cu(OH)2 was prepared on Cu substrate, then KMnO4 was decomposed into MnO2 on the surface of Cu(OH)2 under the hydrothermal condition, and core-shell structure Cu-CuO-MnO2 catalyst was obtained after calcination. The samples were characterized by XRD, SEM, Raman and TG, and the performance of catalytic degradation of methylene blue was investigated. The effects of KMnO4 decomposition reaction time, calcination temperature and the amount of H2O2 on the degradation performance were discussed. The results showed that degradation rate of methylene blue reached 96.4% when the decomposition reaction time was 3 h, the calcination temperature was at 250℃ and the amount of H2O2 was 6 mL. The cyclic utilization of catalyst showed that the degradation of methylene blue was over 94% after 5 cycles, this means that Cu-CuO-MnO2 has good stability, and it has potential application value in the treatment of dye wastewater.
