Abstract
The simple storage of ammonia combined with the tendency to liberate hydrogen without carbon dioxide emissions has made ammonia breakdown popular among the research community in recent years. This review article has discussed the current advances in ammonia breakdown technology for hydrogen generation, focusing on new materials and mechanical designs for catalysis. Moreover, it would help to update the knowledge about the catalytic reaction processes and emphasize the benefits and drawbacks of each strategy. Furthermore, the significance of discovering a cost-effective metal catalyst with better efficiency and higher reliability is also debated. This article may serve as a fundamental resource to scale up information about the catalytic production of hydrogen from ammonia.
