Abstract
Ammonia (NH3), a noxious gas, not merely poses a threat to human beings but also serves as a significant hydrogen carrier. The matter related to its emission is naturally highly deserving of people’s meticulous attention and in-depth research. Taking into account the substantial harm that ammonia inflicts upon the environment and the human body, the storage of ammonia is indisputably an inevitable aspect in the course of green development. Simultaneously, ammonia finds extensive applications and serves as an indispensable raw material for numerous fertilizers, food, explosives, and even medicines. When employed as a fuel, ammonia boasts numerous advantages, rendering it a widely utilized and highly promising gas. Therefore, the storage of ammonia is extremely worthy of profound exploration. Currently, the principal ammonia treatment technologies comprise adsorption, absorption, catalytic conversion, biological treatment, and plasma treatment. The research and development of adsorption materials constitutes the crucial link in ammonia gas adsorption, and the storage materials for ammonia are also highly diverse. This paper integrates a considerable number of various literatures and experiments from multiple perspectives to furnish a comprehensive summary of the current research and achievements in ammonia adsorption and desorption. The materials involved mainly consist of some metal chlorides, metal oxides, zeolites, and MOF materials. Metal chlorides are highly prone to forming amide complexes with ammonia. Metal oxides are a type of compounds composed of metal elements and oxygen elements, which are typically highly stable in nature and have wide-ranging applications in various fields. Research on the utilization of metal oxides as ammonia adsorbents has consistently been a focus for scholars in different countries. The microporous structure of zeolite is extremely well-developed, which results in an exceptionally high specific surface area. This high specific surface area provides a considerable amount of contact space for molecules, thereby significantly enhancing the adsorption efficiency of the adsorbent.
