主　　题：CO_(2)hydrogenation InZrO_(x)+SSZ-13 Propane Oxygen vacancies Acid strength 

摘      要：Direct converting carbon dioxide into hydrocarbon fuels and value-added chemicals would offer a very attractive approach for efficient utilization of CO_(2) as a carbon ***,olefins,aromatics and gasoline have been successfully synthesized by CO_(2) hydrogenation,highly selective conversion of CO_(2) and H_(2) into C_(2+)hydrocarbon is still challenging due to a high C-C coupling barrier and inhibiting the production of other long-chain ***,we report a composite catalyst made of InZrO_(x) and SSZ-13 molecular sieve(InZrO_(x)+SSZ-13),which exhibits 74.5% propane selectivity at 623 *** 8-MR micropores and the higher strength of the acid for SSZ-13 benefit the formation of *** with pure InO_(x) and m-ZrO_(2) the composite oxide InZrO_(x) containing more oxygen vacancies,exhibits to be more readily reduced by H_(2) and easier to adsorb and desorb CO_(2) within the reaction *** those could be beneficial to the activation and conversion of H_(2) and CO_(2).The catalytic performance of InZrO_(x)+SSZ-13 in CO_(2) hydrogenation provides a potential for production of propane.
