Porosity of Composites Formed by Coordination Polymer of Cu-BTC with Phosphotungstic Acid and Their Catalytic Properties in the Preparation of Dimethyl Ether from Methanol

A one-pot method was developed for the preparation of composites containing Cu3(BTC)2 and phosphotungstic acid with controllable content of polyoxometallate in the matrix of a coordination polymer. It was shown that increase of the polyoxometallate content of the composite led to complication in the system of pores in the coordination polymer and to reduction of their size. The catalytic properties of the composites in the formation of dimethyl ether from methanol were studied.
