摘要 

以柠檬酸为络合剂,制备掺杂不同金属的铈基固溶体。XRD表征表明成功合成了铈基固溶体。甲醇和二氧化碳直接合成碳酸二甲酯活性测试结果表明,掺杂镧的固溶体具有较好的活性,加入锌的固溶体活性最差。对掺杂不同金属的铈基固溶体的NH3-TPD和CO2-TPD表征表明,中强酸碱位和强酸碱位是催化剂的活性中心。具有较多中强酸碱位和强酸碱位的铈镧固溶体表现出最好的活性。

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.
