Abstract: Ammonia is a typical toxic pollutant and also one of the main causes of the formation of PM2.5. The emission of industrial tail gases containing a large amount of ammonia not only seriously affects the environment and health of human beings, but also results in serious waste of ammonia sources if directly discharged into the atmosphere. Because of their abundant pore structures and large specific surface areas, good adsorption characteristics and mechanical stability, porous materials have attracted a lot of attention in gas adsorption, especially in ammonia removal. Different porous materials can effectively absorb ammonia through the physical or chemical interaction between ammonia and their special pore structures or action sites. The adsorption method for ammonia removal has the several advantages, such as high selectivity, easy recovery and low energy consumption, so it is widely used in many industrial processes. In this review, the recent research status and progress of ammonia removal using different porous materials were reviewed, mainly focused on the research around the ammonia adsorption performances of zeolite, silica gel, activated carbon, graphene oxide, porous organic polymer, covalent organic frameworks (COFs), metal?organic frameworks (MOFs) materials before and after modification, and the research progress of supported ionic liquids materials for ammonia separation in recent years was also introduced. Ionic liquids, as a class of green medium, have several unique advantages for ammonia removal, such as low vapor pressure, high gas selectivity, high thermal stability, tunable structures and properties. Supported ionic liquids materials can combine the characteristics of both ionic liquids and porous materials, which can break the traditional restriction of ionic liquids in industrial applications and providing a novel pathway for ammonia removal applications. Finally, given the main problems of the current development on ammonia removal and recovery using porous materials, the future research directions and solutions had been put forward.
