Catalysis Letters Aims and scope Submit manuscript

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/Al2O3 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.
