Abstract

Metal–organic frameworks (MOFs) have garnered much attention because of their ability to adsorb gases, which can be tailored by tuning the pore size and MOF–adsorbate interactions through careful choice of ligand and metal. An example of such considered MOF synthesis from Randall Snurr and co-workers at Northwestern University, USA, has led to a material that could be used to remove CO2 from CO2/CH4 mixtures — an important step in the purification of natural gas.
