    Current Research on Gaseous Ammonia Detecting and Capture Technologies
    (Elsevier, 2023-10-27) Akhand, Aamer; Wu, Xiao-Yu
    Ammonia is currently widely used for fertilizers, and it continues to grow as a potential clean fuel source or hydrogen carrier, which may result in growing trace amounts in the atmosphere. Increasing anthropogenic ammonia emissions raises concerns such as disrupting the global nitrogen cycle and negating the greenhouse gas reduction. This review article outlines and compiles recent studies on gaseous ammonia sensing and absorption/adsorption, which could alert or reduce rogue emissions, i.e., unintended anthropogenic releases of ammonia. Different sensors and their characteristics are outlined with a focus on the more popular chemoresistive technologies. Several absorption/adsorption methods from metal-organic frameworks (MOFs) and deep eutectic solvents (DESs) are described and highlighted.
