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.

在此，概述了利用多金属催化剂生产大量分子氢的最新进展，特别是通过烃的蒸汽重整和水煤气变换反应。重点解释了影响当前使用的催化剂的问题，以及在现有催化剂或新催化剂中添加/掺入其他金属如何提高催化剂的活性、选择性和稳定性。我们比较了从文献中选取的关键实例的结果，其中多金属催化剂用于上述反应。甲醇和氨的分解也经过严格分析，重点是地球上丰富的金属元素。
