The water gas shift (WGS) reaction is a critical step in the production of hydrogen, a key reactant in chemicals production, petroleum refining and biomass conversion. Oxide-supported catalysts are typically used for this reaction and the type of support can influence performance. This paper will describe the catalytic, structural and compositional properties of nanostructured carbide supported catalysts. Nanostructured carbides are attractive candidates for use as support materials because of their high surface areas and refractory nature. Rates for some of the carbide supported catalysts were significantly higher than those for the most active oxide-supported catalysts. Characterization using techniques including x-ray absorption spectroscopy provided some insight regarding the active sites on these highly active WGS catalysts.
