英文摘要	Cao-zro2 catalysts with cao content ranging from 10% to 50% were prepared by coprecipitation and their catalytic performances were evaluated in the synthesis of dimethyl carbonate from propylene carbonate and methanol. the characterization by xrd, fimr, bet, icp, xps and co2-tpd indicated that when cao content was higher than 30%, cao segregated at grain boundaries and the catalysts showed high activity but low stability. whereas, ca2+ ion substituted for zr4+ ions in the host lattice to form homogeneous cao-zro2 solid solution when cao content changed from 10% to 30%, as a result, the base strength were enhanced and the catalysts showed both high activity and stability towards the synthesis of dimethyl carbonate. the formation of homogeneous cao-zro2 solid solution was responsible for the stability of catalysts.
