description

L.N.M and R.E.M wish to acknowledge the financial support from the EPSRC industrial CASE award (grant EP/N50936X/1). A.T and G.B would like to thank the financial support from the Fondo per il finanziamento delle attività base di ricerca (grant PJ-RIC-FFABR_2017). Metal-organic frameworks (MOFs) are a class of porous materials that show promise in the removal of Toxic Industrial Chemicals (TICs) from contaminated airstreams, though their development for this application has so far been hindered by issues of water stability and the wide availability and low cost of traditionally used activated carbons. Here a series of three MOF-activated carbon composite materials with different MOF to carbon ratios are prepared by growing STAM-17-OEt crystals inside the commercially available BPL activated carbon. The composite materials display excellent water stability and increased uptake of ammonia gas when compared to unimpregnated carbon. Such properties make these composites very promising in the fields of air purification and personal protective equipment. Postprint Peer reviewed
