摘要：
This study used solvothermal method to synthesize two vanadium-doped bimetallic catalysts, and compared their heterogeneous Fenton degradation performance of Methylene blue. The samples were characterized by SEM, XRD, XPS, etc. The two catalysts showed good capacities for degradation of Methylene blue in both acidic to alkaline solutions (pH=3-10). The highest removal rate of Methylene blue by the Cu-V composite material was 95.60% at pH=10, while that by the Fe-V composite material reached 96.6% at pH=3. Both the Cu-V and Fe-V composite materials had good reusability. After six consecutive runs at pH=7, the removal rate of methylene blue remained at 79.16% and 68.22%, respectively. The mechanism of the catalytic reaction system has been preliminarily discussed. The hydroxyl radical is the main active species, but the catalytic mechanisms of the two catalysts are slightly different. © 2021, Chemical Industry Press Co., Ltd. All right reserved.
