Abstract

Removal of highly toxic and corrosive hydrogen sulphide from gas flows is of paramount importance for the environment and in industrial processes. This contribution reports a simple strategy to obtain materials for efficient hydrogen sulphide removal under humid conditions by functionalization of open-metal sites in metal-organic frameworks (MOFs) with polyamines.
