Abstract

The invention discloses a porous nickel-based hydrogen-evolving electrode composite material. The foamed metal of the porous nickel-based hydrogen-evolving electrode is used as a base material, and a S-La-Ni alloy is electrolytically deposited through an ionic liquid, and then the aluminum is removed by corrosion treatment in an alkaline solution to obtain a porous material. Electrode, then sulfur modified by heat treatment, the specific surface area of ​​the composite material is 20‑23g / m 2 , good hydrogen evolution catalytic activity and excellent chemical stability.

Description

technical field [0001] The invention relates to a porous nickel-based hydrogen evolution electrode composite material, and mainly relates to the field of preparing alkaline catholyte by electrolyzing water. 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 research that long-term drinking can be used as an auxiliary means of disease prevention and ...
