Abstract

This study focuses on investigation of the effects of magnesium on catalyst and moisture in reactant on the catalytic activity in CO oxidation using Pt catalysts. The CO conversion rate over Pt-Mg/Al₂O₃ with temperature was higher than that of Pt/Al₂O₃. With the reactants containing moisture, the CO conversion rate over Pt-Mg/Al ₂O₃ was significantly improved. It is observed that addition of magnesium to Pt catalysts enriches the hydroxyl group with the increase of basicity and the content of Pt⁰which is weakly interacted with CO.
