Abstract：As one of the most important secondary energy sources, hydrogen plays an important role in the substitution of fossil fuels. Due to the advantages of high hydrogen storage, low cost, easy liquefaction, and no COx generation from decomposition, ammonia has been extensively studied as hydrogen carrier. The core technology of ammonia decomposition to hydrogen production lies in how to improve the ammonia conversion rate and reduce the reaction temperature of ammonia decomposition. This paper summarizes the research on precious metals, non-precious metals, bimetallic catalyst and other catalysts in ammonia decomposition for hydrogen production in recent years. It analyzed the impact of various factors such as particle size, morphology, loading, carrier, catalyst promoter, metal-to-support interaction on catalytic activity. Furthermore, it compared the advantages and disadvantages of catalysts in different systems and proposed improvement measures and future development directions for precious metal-based catalysts to design highly active catalysts with low loading.
