Removal of chlorine gas by an amine functionalized metal–organic framework via electrophilic aromatic substitution

Abstract

Chlorine gas is removed from airstreams with an amine functionalized metal–organic framework via an electrophilic aromatic substitution reaction producing HCl, which is subsequently neutralized by the substrate.

Abstract

Here we report the removal of chlorine gas from air via a reaction with an amine functionalized metal–organic framework (MOF). It is found that UiO-66-NH ₂ has the ability to remove 1.24 g of Cl ₂ per g of MOF via an electrophilic aromatic substitution reaction producing HCl, which is subsequently neutralized by the MOF.
