The performance of the two newly developed bimetallic catalysts based on the precursor, Mo/Al2O3, was com-pared for reverse water gas shift (RWGS) reaction. The structures of the precursor and the catalysts were studied using X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET) analysis, inductively coupled plasma-atomic emission spec-trometry (ICP-AES), CO chemisorption, temperature programmed reduction of hydrogen (H2-TPR) and scanning electron microscopy (SEM) techniques. The activity of Fe-Mo and Co-Mo catalysts was compared in a ifxed bed reactor at different temperatures. It is shown that the Co-Mo catalyst has higher CO2 conversion at all temperature level. The time-on-stream (TOS) analysis of the activity of catalysts for the RWGS reaction was carried out over a continuous period of 60 h for both catalysts. The Fe-Mo/Al2O3 catalyst exhibits good stability within a period of 60 h, however, the Co-Mo/Al2O3 is gradually deactivated after 50 h of reaction time. Existence of Fe2(MoO4)3 phase in Fe-Mo/Al2O3 catalyst makes this catalyst more stable for RWGS reaction.
