Abstract
La–Ce–silica mesoporous SBA-15-type material has been rapidly synthesized using microwave technique and characterized by XRD, FT-IR, DRS, and low temperature N2 adsorption–desorption measurement. The results show the La and Ce were successfully incorporated into the framework of SBA-15 molecular sieve and the synthesized material not only retains the hexagonal order and physical properties of purely siliceous SBA-15 but also possesses high surface area and narrow pore-size distribution. Further, the obtained material La–Ce–SBA-15 was used as catalyst support to load active metal Pt for CO oxidation reaction. The results of experiment indicate that the catalytic activity of Pt/La–Ce–SBA-15 is higher than that of the Pt/SBA-15 and Pt/La/Ce/SBA-15.
