Abstract

The invention discloses a preparation method and application of a Co3O4 nano porous cathode coating. The method comprises the following steps of: taking Ni or raney nickel as a substrate, mixing Co3O4with Al, coating the mixture on a magnetron sputtering target material, coating the mixture on the substrate in a magnetron sputtering manner to form a compact mixture coating, etching the surface ofthe compact mixture coating by using alkali liquor, and conducting cleaning and drying to obtain the porous Co3O4 nano coating. On the one hand, the chemical stability of the cathode electrode is improved, so that the cathode electrode is not easy to corrode in the reaction process, and on the other hand, the reaction process is not influenced due to the porous material. According to the method,the cost generated by electrode corrosion can be reduced, performance reduction caused by impure electrolyte solution due to corrosion can be avoided, and the method has a great application prospect.

Description

technical field [0001] The invention belongs to the technical field of preparation of catalyst electrodes, in particular to a Co 3 o 4 Preparation method and application of nanoporous cathode coating. Background technique [0002] With the advancement of human science and technology, various electrode catalytic technologies emerge in endlessly! The general trend is to develop towards "nanoization", that is, to control the microstructure of catalytic materials through various methods and means, to develop and change in the direction expected by people, and then to realize the excellent performance of the microstructure of catalytic materials. At present, although people have obtained many nanometerization methods of catalytic materials through research, such as: laser ablation method, chemical vapor deposition method, thermal vapor deposition method, template method, hydrothermal method, etc., they are all facing the test of industrial application . Especially there are m...
