The excellent hydrogen analysis performance is mainly due to the Good Conductivity of Ni/rGO composite electrodes, large surface area, high interface density and synergy between nickel particles and graphene sheets. Nitrogen-doped carbon spheres (NCCs) are prepared by simple hydrothermal method, where glucose is used as a carbon source and ethylamine is used as a nitrogen source, and Ni/NC composite electrodes are then prepared by efficient electrodesis. The excellent catalytic hydrogen analysis activity of the modified electrode is mainly due to the rich active site of the Ni/NC composite electrode, the unique nuclear-shell structure, good conductivity, and the synergy between the nickel layer and NC. Cai Naicai and others reported the preparation method of the NiMo-RuO2 composite catalytic layer, the surface shape and surface roughness factor of the electrode, the influence of RuO2 content on hydrogen over-potential, the steady-state cathode polarization curve and electrochemical reaction dynamics parameters of the electrode, and the stability of the electrode in the alkali solution containing Fe3-ion. The introduction of RuO2 particles in Ni-Mo alloys by experiments increases the real reaction area of the electrode, improving the catalytic activity of the electrode and the ability to resist the de-activity of Fe3-plus ions.

The excellent hydrogen evolution performance is mainly attributed to the good conductivity, large specific surface area, high interface density and the synergistic effect between nickel particles and graphene sheets. Nitrogen doped carbon spheres (NC) were prepared by a simple hydrothermal method, in which glucose was used as carbon source and ethylenediamine as nitrogen source. The excellent catalytic hydrogen evolution activity of the modified electrode is mainly attributed to the rich active sites, unique core-shell structure, good conductivity, and the synergistic effect between the nickel layer and NC.
