FIELD: metallurgy.

SUBSTANCE: invention relates to a technology for producing nanostructured zinc oxide doped with copper, which can be used as a photocatalyst. The method for producing a photocatalyst based on nanostructured copper-doped zinc oxide includes introducing a mixture of an oxygen-containing zinc compound and an oxygen-containing copper compound into ethylene glycol, vacuum filtration, washing with acetone, drying, and subsequent calcination. A mixture of crystalline zinc oxide and crystalline copper carbonate, taken in a stoichiometric ratio, is added to ethylene glycol containing concentrated formic acid in an amount of 9-14 vol.% of the total volume of ethylene glycol, and preheated to 50°C, while ethylene glycol is taken in excess of 10-15% of the stoichiometric ratio of the mixture of zinc oxide and copper carbonate.

EFFECT: simple and reliable method for obtaining a photocatalyst based on copper-doped zinc oxide with nanoparticles in the form of nanofibers or nanospheres, which provides an increase in the active surface of the photocatalyst and, consequently, its photocatalytic activity.
