Abstract

The invention relates to an efficient Ni/Ni(OH)2 hydrogen evolution electrode, which is characterized in that nickel sulfate hexahydrate and nickel chloride are adopted as sources of nickel elements,and nickel and hydroxide nanoparticles thereof are uniformly doped into a catalyst layer through a direct-current electrodeposition method in combination with subsequent oxidation-reduction treatment,so that the efficient Ni/Ni(OH)2 hydrogen evolution electrode is prepared. The invention also relates to a preparation method of the high-efficiency Ni/Ni(OH)2 hydrogen evolution electrode, which comprises the following steps: (1) pretreating the conductive substrate; (2) carrying out DC electrodeposition to prepare a catalyst layer formed by stacking nano flaky nickel and hydroxide thereof; and(3) carrying out anodic oxidation treatment to obtain the Ni/Ni(OH)2 hydrogen evolution electrode. The Ni/Ni(OH)2 hydrogen evolution electrode is scientific and reasonable in design and has the advantages of being high in catalytic hydrogen evolution activity, low in cost, low in energy consumption, stable in use, good in electrical conductivity and the like. The invention provides the Ni/Ni(OH)2hydrogen evolution electrode and the preparation method thereof with relatively high innovativeness.

Description

technical field [0001] The invention belongs to the field of hydrogen preparation, and relates to an electrode, in particular to a high-efficiency Ni / Ni(OH) 2 Hydrogen evolution electrode and its preparation method. Background technique [0002] Modern human life is inseparable from energy. Energy is the foundation of modern economic development and an important strategic material for social development. With the consumption of traditional fossil fuels and the aggravation of environmental pollution, we urgently need to develop a new renewable energy source. At present, the main energy sources for research include hydropower resources, nuclear energy, wind energy, biomass energy, solar energy, hydrogen energy, shale gas, ocean energy, etc. Among the many new energy sources, hydrogen energy is one of the most potential energy sources. [0003] At present, the main source of hydrogen energy is the production of hydrogen from natural gas, coal, or chemical by-products. More t...
