Abstract

An S-shaped gas isotherm pattern displays high working capacity in pressure-swing adsorption cycle, as established for CO₂, CH₄, acetylene, and CO. However, to our knowledge, this type of adsorption behavior has not been revealed for NH₃ gas. Herein, we design and characterize a hydrogen-bonded organic framework (HOF) that can adsorb NH₃ uniquely in an S-shape (type IV) fashion. While conventional porous materials, mostly with type I NH₃ adsorption behavior, require relatively high regeneration temperature, this platform which has significant working capacity is easily regenerated and recyclable at room temperature.
