Abstract

A two-dimensional (2D) metal–organic framework (MOF) named NUS-5 was synthesized using a bi-functional ligand 4-pyrazolecarboxylic acid (PyC) containing both carboxylate and pyrazole moieties. NUS-5 is composed of porous grids stacked together into a 2D layered structure exhibiting ultra-micropores. It displays remarkable thermostability and excellent selectivity towards sorption of CO₂ over N₂, making it a good material candidate for post-combustion CO₂ capture.
