Abstract: The present invention discovered a new type of water gas shift reaction catalysts. A catalyst of this type comprises a catalyst support and two catalytically active components. The catalyst support is a high surface area material, such as silicon oxide, aluminum oxide, or carbon power. The two catalytically active components are a metal oxide component and a metal component. The said metal oxide component is molybdenum oxide. The said metal component can be either a noble metal selected from Pt, Pd, Ru, Os, Ir and Au or a binary alloy that is formed from the noble metals just mentioned.
