abstract Herewith, an overview is provided on the recent developments in the utilization of multimetallic catalysts to produce large amounts of molecular hydrogen, especially via the steam reforming of hydrocarbons and the water-gas shift reaction. Emphasis is given on the explanation of the problems affecting the currently used catalysts and how the addition/incorporation of other metals in available or new catalysts may lead to improved catalyst activity, selectivity and stability. We compare results from selected key examples taken from the literature where multimetallic catalysts are used for the aforementioned reactions. The methanol and ammonia decompositions are also critically analyzed, with focus on Earth-abundant metal elements.
