Abstract
Hydrogen (H2) is the lightest known molecule; hence, its compression or liquefaction is highly energy-intensive. One of the promising ways to easily store and transport hydrogen is via the use of chemical carriers such as ammonia (17.8 wt%H2). Synthesis of ammonia, however, accounts for 2% of global energy use and 1.2% of anthropogenic carbon dioxide emissions. So, catalysts play a significant role in mitigating these by lowering the temperature and pressure required for the reaction. In this paper, Arash and his team have studied the effect of chemical promoters on the reactivity of perovskite-supported catalysts. They identified which promoter works the best and described the mechanism of the reaction chemistry of thermochemical ammonia synthesis when using these catalysts. Their findings highlight significant insights into the design of new catalysts for such a high-in-demand reaction.
