| 中文摘要: |
| 采用溶胶凝胶法制备La-ZnO/SBA-15催化剂，并采用XRD、TG-DSC、XPS、TEM、SEM、N2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，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。 |
| 英文摘要: |
| 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. |
