FIELD: chemistry.
SUBSTANCE: invention relates to a method of obtaining nanowhisker structures of oxide tungsten bronzes on a coal material, in which electrolysis is carried out in a pulse potentiostatic mode with overvoltage of 300 mW in melt, which contains 30 mol. % K2WO4, 25 mol. % Li2WO4 and 45 mol. % WO3, with the application of a platinum anode, and electroprecipitation is carried out on a cathode from the coal material with the high specific surface, before supplying on the electrode of an overvoltage impulse the cathode is soaked with melt during the time, sufficient for soaking, but insufficient for active burning-out of carbon from the coal cathode.
EFFECT: application of the claimed method makes it possible to obtain nanowhisker structures of tungsten bronzes on the coal material, which can be applied as high-activity catalysts, possessing technological properties for processes of organic and petrochemical synthesis.
