Photothermal-assisted NH₃ release in a bipyridinium-functionalized metal-organic framework adsorbent.

ABSTRACT: Widespread deployment of NH₃-adsorbing MOF materials remains challenging due to the significant energy-penalty of regeneration. In this work, we address this limitation by integrating photothermal technologies into a bipyridinium-functionalized MOF matrix, enabling effective NH₃ desorption in a more eco-friendly and sustainable manner. This MOF adsorbent exhibits selective NH₃ capture via specific hydrogen bonding interactions, rendering it suitable for purifying effluent gases in industrial NH₃ synthesis. The NH₃ adsorption process is accompanied by an obvious color change due to the formation of bipyridinium radicals through an electron transfer reaction between NH₃ molecules and bipyridinium ligands.
