Abstract
The paper presents a new porous coating of electrodes for water electrolyzers with an alkaline electrolyte, as well as methods for its modification with catalysts for the reaction of hydrogen and oxygen evolution. The coating is formed from a suspension of nickel-cobalt powder in an electroplating bath for applying a nickel-cobalt coating and is characterized by an acicular structure and a developed specific surface. Nickel-cobalt powder is obtained by thermal decomposition of mixed nickel-cobalt formate in 1,4-butanediol, which is a modifying additive for nickel plating bath. The results of studies of new electrode materials by physicochemical and electrochemical methods are reported.
