Preparation of Promoted Pt/SBA-15 and Effect of Cerium on the Catalytic Activity over Carbon Monoxide Oxidation Conversion Reaction
Abstract
Pt/SBA-15 catalysts are modified by cerium dopant and agent. Experimental results show that the catalytic
activities of Pt/SBA-15 can be deeply promoted by the introduced cerium species, especially while both cerium
dopant and cerium agent are introduced. The promoted catalytic activities are due to the occurrence of new coordination environments, promoted physicochemical properties of Pt loading created by both introduced cerium species, and the strong metal-support interactions created by the cerium loading.
