ELECTROCHEMICAL METHOD FOR PRODUCING NANOFIBERS OF METALLIC COPPER Russian patent published in 2021 - IPC C25C5/04 C25F3/04 C25F1/12 B82Y40/00 

FIELD: chemistry.

SUBSTANCE: invention relates to the electrochemical production of nanofibers of metallic copper with a developed surface, so-called copper “nano-cotton”, based on which, materials with specific morphology and special properties can be obtained, for example, to create substrates of catalysts for electrodeposition of materials with specified parameters, for use in medicine and biotechnology, etc. In a method, a copper-aluminum alloy containing 50 wt.% of copper and 50 wt.% of aluminum is processed with direct current in an electrolyte melt from a salt mixture containing 40 mol.% of lithium carbonate, 30 mol.% of sodium carbonate, 30 mol % of potassium carbonate, while anodic processing of the copper-aluminum alloy is carried out at a temperature of 500°C and current density of 0.02 A/cm² with the formation of porous substrate, which is a layer of products of the interaction of the processed alloy with the electrolyte melt, and the formation of metallic copper nanofibers on the mentioned porous substrate.

EFFECT: high speed of the process of forming a layer of copper nanofibers on porous substrate is provided in the absence of the influence of melt components on the resulting nano-porous copper.
