The composition of a self-regulating complex electrolyte based on sodium citrate, nickel salts and strontium molybdate for obtaining a Ni-Mo coating was developed: (mol/l) 0.2 NiCl2; 0.04 SrMoO4; 0.3 Na3C6H5O7, pH9.0, and effective modes of its application were established - i = 0.5...2.5 A/dm2, t = 22, 70°C, Vp = 300 rpm. To obtain coatings of the Ni-Mo-B system with a boron content of 0,9...2,3 % mass. 50 and 100 g of amorphous boron were additionally added to the electrolyte, respectively. The developed Ni-Mo and Ni-Mo-B coatings are able to reduce the overvoltage of hydrogen release in alkaline environments and can serve as a promising catalyst for the production of green hydrogen.
