Abstract 

Ceria-Based solid solution is prepared through precipitation method with citric acid as complexing agent. The solid solution was successfully synthesized based on the result of XRD. La-Ce solid solution exhibited better catalytic activity than the others. The acidic and basic properties of ceria-based solid solution were measured by NH3-TPD and CO2-TPD. The moderate and strong acid-base sites were favorable for the formation of DMC. La-Ce solid solution had a good performance in DMC formation due to the presence of more moderate and strong acid-base sites on catalyst surface.
