摘要：

Ceria catalysts were found active and selective to the oxidehydrogenation of ethane (ODE) with CO2 and the actual contribution for C2H4 formation from heterogeneous catalysis was 75-55% in the range 953-993 K. The presence of calcium ions in solid solution in the ceria crystalline network increased significatively the selectivity to ethene and the efficiency of CO2 as oxidant in the heterogeneous reaction.
