Selective Formation of H2 in the Water-Gas Shift Reaction over Fe-Mn/TiO2 Prepared by New Method

In the present study, a complex of [Fe(bpy)3][Mn(H2O)6].2H2O was synthesized and characterized by various methods. This complex was dispersed on the TiO2 as support, and after thermal decomposition, nanocatalyst of Fe-Mn/TiO2 was prepared. This nanocatalyst was characterized by TGA, DSC, SEM, BET, TEM and XRD and applied as catalyst in the water-gas shift reaction. Also this nano-catalyst was prepared by co-precipitation and impregnation methods as references catalysts. Studies showed that each catalyst has the best catalytic performance at 400ºC and the catalyst which was prepared by thermal decomposition of inorganic complex has the highest catalytic performance compared to the other. Stability test for nano-catalyst was performed at 400ºC (optimum temperature) and confirmed that the nano-catalyst are stable for 12h.
