In the preferential CO oxidation under H 2 -rich gas, CO conversion and selectivity of CO oxidation were enhanced by the addition of alkali metal ions (M=Li, Na, K, Rb, Cs) to Pt/Al 2 O 3 in the range of the molar ratio (M/Pt) lower than 3, and TOFs monotonously increased along with the basicity strength of added alkali metal ions. In contrast, in the range of M/Pt⩾5, the order...
CeO2–ZrO2 solid solution catalysts are very effective for the selective synthesis of dimethyl carbonate from methanol and CO2. The activity was much dependent on the calcination temperature. The higher the calcination temperature, the higher the activity of the catalyst for DMC formation, though the BET surface area is lower on the catalyst calcined at higher temperature.
