一个S形的气体等温线模式显示高的工作能力，在变压吸附循环，建立为CO2，CH4，乙炔，和CO。然而，据我们所知，这种类型的吸附行为尚未透露为NH3气体。在这里，我们设计和表征的氢键有机框架（霍夫），可以吸附NH3独特的S形（IV型）的方式。传统的多孔材料大多具有I型NH3吸附行为，需要相对较高的再生温度，而这种具有显著工作容量的平台在室温下易于再生和回收。
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.
