| 摘 要： | 采用溶胶凝胶法制备La-ZnO/SBA-15催化剂,并通过XRD、TG-DSC、XPS、TEM、SEM、N_2吸附脱附等表征分析La-ZnO/SBA-15的组成和性质,考察其对孔雀石绿溶液的催化活性。结果表明,掺杂后的SBA-15仍保持有序的二维六方结构,当n(Zn)∶n(Si)=1时,可见光照射2h,孔雀石绿降解率达99. 8%。动力学研究表明,催化剂对孔雀石绿溶液的降解符合一级反应动力学。

| Abstract: | La-ZnO/SBA-15 catalyst was prepared by sol-gel method. The composition and properties of La-ZnO/SBA-15 were characterized by XRD, XPS, SEM and N2 adsorption and desorption. Investigate its catalytic activity on malachite green solution. The results showed that the doped SBA-15 still maintains an ordered two-dimensional hexagonal structure. When n(Zn):n(Si)=1, visible light irradiation for 2 h, the degradation rate was 99.8%. Kinetic studies show that the degradation of the malachite green solution by the catalyst is consistent with the first-order reaction kinetics. |
