Abstract

Abstract: NH3 has been used in wide applications, such as fertilizers, hydrogen sources, and working fluids, where proper NH3 adsorbents are required to minimize human health risks in daily NH3 exposure as well as to achieve energy efficiency in energy conversion systems. As NH3 operating pressure differs from each usage, the structure and properties of the NH3 adsorbent need to be optimized in each NH3 operating pressure. Metal–organic frameworks (MOFs) have emerged as promising NH3 adsorbents, which would be customizable for different NH3 pressures due to great structural tunability. We introduce up‐to‐date reports with MOFs as NH3 adsorbents and classify them by the NH3 pressure, from high in adsorption heat pumps to extremely low in daily life sensing. MOFs with high NH3 adsorption capacity and durability are suggested in different NH3 pressure ranges, and their structural factors are discussed to help design high‐performance MOFs for NH3 adsorption in different NH3 pressures.
