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. 查看全文查看/发表评论下载PDF阅读器 相关附件:版权转让声明书 -->
