Abstract: 

Currently, a large number of studies on alkaline water electrolysis are being carried out with the aim of reducing the specific energy costs for the hydrogen evolution reaction and the oxygen evolution reaction. This work is devoted to the methods of synthesis of highly dispersed composite coating on the surface of nickel foam and the methods of the formation of bi- and ternary catalytic alloys based on molybdenum using electrochemical deposition. During the study of the samples morphological and element-by-element analyses were carried out and the activity indicators of the synthesized highly effective catalytic coatings were obtained.

Key words:
