Generally, water gas shift (WGS) reaction is a very important step in the industrial production of hydrogen, ammonia and other bulk chemicals utilizing synthesis gases. In this paper, we are reporting WGS reaction carried out in our research group for the application of hydrogen station and fuel processor. We prepared various Mo 2 C, PtNi-based and Cu-based catalysts for low temperature WGS reaction. The characteristics of the prepared catalyst were analyzed by N 2 physisorption, CO chemisorptions, XRD, SEM and TEM technologies, and compared with that of commercial Cu-Zn/Al 2 O 3 catalyst. It was found that prepared catalysts displayed reasonably good activity and thermal cycling stability than commercial LTS (Cu-Zn/ Al 2 O 3 ) catalyst. It was found that the deactivation of commercial LTS catalyst during the thermal cycling run at 250°C was caused by the sintering of active metal even though it shows high activity at less than 250°C. The deactivation of Mo 2 C catalyst during the thermal cycling run was caused by the transition of Mo d? , Mo IV and Mo 2 C on the surface of Mo 2 C catalyst to Mo VI (MoO 3 ) with the reaction of H 2 O in reactants. However, they showed higher stability than the commercial LTS catalyst during thermal cycling test. The Pt-Ni/CeO 2 catalyst after the thermal cycling shows slightly deactivation due to the sintering of Ni metal. Among Cu-based catalysts, it was found that CuMo/Ce 0.5 Zr 0.5 O 2 catalyst has higher WGS activity and stability over commercial LTS catalyst. The results suggested that Pt-Ni/CeO 2 and Cu-Mo/Ce 0.5 Zr 0.5 O 2 catalysts are desirable candidates for application in hydrogen station and fuel processor system even though all other catalysts deactivated slowly during the thermal cycling run.

“…Previous investigations on Pt/CeO 2 catalysts have shown that strong metal-ceria interactions, by formation of solid solution in the mixed oxides catalysts, can be achieved by combustion synthesis of samples [13,14]. The strong metal-to-support interaction appeared as one of the reasons of the observed high catalytic activity and stability during the hydrocarbons' partial oxidation and oxidative steam reforming (OSR).…”

“…The result of our work showed that the main gaseous products of methane partial oxidation are CO 2 and H 2 when the CH 4 /O 2 ratios are between 2:1 and 1:1 at low temperature. These results may provide an alternative way to yield hydrogen feeds containing very poor-CO for fuel cells [33].…”
