Synthesis of Composite Materials Resistant to a Change in Medium Acidity from Cu-BTC (MOF-199) and Activated Carbons

To enhance the resistance of a metal-organic frameworks(MOF) to a change in the medium pH composite materials are synthesized from Cu-BTC (MOF-199) and activated carbons of various brands (AR-V, AGN-2, ART-1, BAU-A, MeKS). It is shown that the highest stability is exhibited by a material synthesized using activated carbon AR-V with the highest acidity of the surface as a matrix. The targeted increase in the acidity of the surface of carbon matrices due to their preliminary oxidation leads to the formation of metal-organic composite materials more resistant to acidic or alkaline media. © 2020, Pleiades Publishing, Ltd.
