Section periphery towards [28] In like foamed nickel substrate was prepared by electrodeposition of amorphous Ni-S-Co alloy coated electrodes. In scanning electron microscopy (SEM) and X-ray diffraction (XRD) surface morphology and microstructure, an electrochemical test method for analyzing the electrochemical behavior of the coating. The results show that the coating obtained was amorphous structure, and the surface of the fine particles having a large specific surface area; preferably hydrogen evolution catalytic properties of amorphous Ni-S-Co alloy electrode, with Ni and Ni-S as compared to electrodes having a relatively low hydrogen overpotential higher exchange current density and low apparent activation energy; KOH alkali solution after the activation treatment, the coating surface of the particles becomes small, increase active surface area, hydrogen evolution performance has been enhanced. Hydrogen evolution catalytic properties of nickel foam support Pr2O3 catalysts, a nickel-based alloy, Ni-S, foam Fe-Cr-Ni alloy or the like are also reported.

Zhou Ke dynasties, such as foam nickel as the base using electrodelizent method to prepare amorphous Ni-S-Co alloy coating electrodes. The electrochemical behavior of the coating is analyzed by scanning the electromirror (SEM) and X-ray diffraction (XRD) to observe the surface morphology and microstructure. The results show that the coating obtained is amorphous structure, the surface particles are small and rich in surface area, the hydrogen-destructing catalytic performance of the amorphous Ni-S-Co alloy electrode is better, and compared with the Ni and Ni-S electrodes, there is a lower hydrogen hydrochemical overelectroator, high switching current density and lower apparent activation energy, and the KOH KOH is through KOH After activation treatment of alkali solution, the surface particles of the coating become fine, the active surface area increases, and the hydrogen analysis performance is enhanced. The hydrolysis catalytic properties of foam nickel carrier Pr2O3 catalyst, foam nickel-based Ni-S alloy, foam Fe-Cr-Ni alloy, etc. are also reported.

The amorphous Ni-S-Co alloy coating electrode was prepared by electrodeposition method using foam nickel as matrix in Zhou Ke Chao [28]. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) were used to observe the surface morphology and microstructure of the coating. The results show that the obtained coating is amorphous structure with fine surface particles and rich surface area; the amorphous Ni-S-Co alloy electrode has better hydrogen evolution catalytic performance, lower hydrogen evolution overpotential, higher exchange current density and lower apparent activation energy compared with Ni and Ni-S electrodes; after KOH alkali solution activation treatment, the surface particles of the coating become smaller, With the increase of active surface area, the hydrogen evolution performance is enhanced. The catalytic performance of nickel foam supported Pr2O3 catalyst, foamed nickel based Ni-S alloy and foamed Fe-Cr-Ni alloy has also been reported.<br>
