英文摘要: A high dispersion of CeO2 within the pores of an SBA-15 mesoporous silica was achieved via deposition precipitation(DP) method, and Pt/CeO2/SBA-15 catalyst was prepared by further depositing Pt on CeO2-modified SBA-15. UV-Vis diffuse reflectance spectra show that intimate contact is formed at Pt-CeO2 interface, which is in favor of the transfer of electrons from CeO2 to Pt and formation of oxygen vacancies. The CO temperature-programmed reduction(CO-TPR) verified the enhanced reducibility of the surface oxygen on CeO2 over Pt/CeO2/SBA-15-DP catalyst.
