ELECTROCHEMICAL METHOD OF PRODUCTION OF COPPER OXIDE NANOWHISKERS Russian patent published in 2021 - IPC C01B13/14 C01G3/02 C25B1/00 B82B3/00 B82Y40/00

Abstract RU 2747920 C1

FIELD: chemistry.

SUBSTANCE: invention relates to electrochemical synthesis of nanomaterials, namely to an electrochemical method for production of copper oxide nanowhiskers. The method includes electrolysis of a polytungstate melt in a pulsed potentiostatic mode using a platinum anode and copper foil as a cathode, wherein a polytungstate melt containing an equimolar mixture of K₂WO₄ - Na₂WO₄ (1:1) and 35% mol. WO₃ undergoes electrolysis in a pulsed potentiostatic mode, wherein the voltage pulse value equals 0.975 V with a duration of 0.1 s.

EFFECT: proposed method allows producing copper oxide nanowhiskers with a large length to thickness ratio in a single stage.
