摘要：The direct synthesis of La-SBA-15 mesoporous material by two-step synthesis method was reported. The effect of pH value during the process on the incorporation of La into the framework of SBA-15 was investigated, and XRD, UV-vis, FT-/R, and ICP were used to characterize the obtained La-SBA-15. The experimental results showed that a large amount of La could enter SBA-15 framework under suitable pH value while a highly ordered mesostructure of samples containing La was retained. In addition, the obtained La-SBA-15 exhibited good catalytic performance in the combustion of trichloroethylene.
