Abstract

The invention discloses a preparation method of a cathode for weak alkaline beauty water. The preparation method comprises the following steps: using porous nickel-based hydrogen evolution electrode foam metal as a base material, carrying out electrolytic deposition on an S-La-Ni alloy by using an ionic liquid, removing aluminum by corrosion treatment in an alkaline solution to obtain a porous electrode, and carrying out sulfur modification by heat treatment. When the weak alkaline beauty water is prepared by electrolyzing water, extremely high catalytic activity and chemical stability can be shown.

Description

technical field [0001] The invention relates to a method for preparing a cathode for weakly alkaline cosmetic water, which belongs to the preparation of weakly alkaline ionized water by electrolyzing water, and in particular to a method for preparing a cathode electrode in an electrolysis process. Background technique [0002] Electrolyzed reduced water is a kind of safe drinking water, which is weakly alkaline (pH>7); the water molecule cluster is about 5-6 water molecules, and the movement speed in the body is 11-13 water molecules in pure water or tap water Twice of that, the molecular activity is relatively high, so a large amount of small molecule water has different functions; high oxygen content, negative potential, can remove peroxides in the body, and have the effect of disease prevention and anti-aging; rich in ionic water minerals. Electrolyzed reduced water fully complies with the hygienic standards of drinking water in my country, and it has been proved by...
