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 detecting and absorption/adsorption, which could alert or reduce rogue emissions, i.e., unintended releases of ammonia. Different sensors and their characteristics are outlined with a focus on the more popular chemoresistive technologies. Several absorption/adsorption methods for ammonia capture using metal-organic frameworks (MOFs) and deep eutectic solvents (DESs) are described and certain research highlighted.enammoniagas sensoradsorptionabsorptionArticle
