The Development Prospects and Potential of High Specific Surface Area Materials: A Review of the Use of Porous Framework Materials for the Capture and Filtration of Ammonia.

Ammonia is one of the most widely produced inorganic chemicals, with extensive applications in the military, agricultural, and industrial sectors. However, its strong stimulation and corrosive properties pose significant health risks, as long-term exposure to ammonia environments can lead to respiratory tract damage, loss of consciousness, and even cardiopulmonary dysfunction. Over the years, researchers have focused on exploring suitable materials for ammonia adsorption fields such as activated carbon and zeolites. Porous framework materials (PFMs), including metal-organic frameworks, covalent organic frameworks, and hydrogen-bonded organic frameworks, have emerged as possible ammonia adsorption materials due to their high specific surface area, pore size, and structural adjustability. This review focuses on the research and application of materials with excellent adsorption based on PFMs for ammonia adsorption, highlighting their potential applications and providing insights into future developments in this field.
