Hydrogenation Reaction of CO_2 by Using FSM-16 and SiO_2 Supported Rh Catalysts
Hydrogenation reaction of CO2 over Rh/FSM-16 and Rh/SiO2 catalysts prepared by impregnation method was carried out. The Rh/FSM-16 catalyst showed higher CO2 conversion and turnover frequency than Rh/SiO2 one. The main product was CO over SiO2 supported catalyst, but it was CH4 over FSM-16 supported one irrespective of reaction temperature. From the results of TEM and H2 chemisorption, the mean particle size of Rh for Rh/FSM-16 was smaller than that for Rh/SiO2. The ratio of chemisorbed CO to chemisorbed H was smaller for Rh/FSM-16 catalyst than Rh/SiO2 one. It was suggested that this finding reflected the difference in product selectivity of CO2 hydrogenation between FSM-16 and SiO2 supported Rh catalysts.
