Abstract

The invention relates to an electrode as well as a preparation method and application thereof. The electrode takes titanium or a titanium alloy as a base material, wherein a composite material coating is coated on the outer surface of the base material; the composite material layer is prepared from composite materials solution through coating, drying and sintering; the composite materials solution is nanometer solution formed through dissolving transition metal elements in ethyl alcohol; the nanometer solution takes particles of transition metal as solutes; the transition metal elements are iridium, platinum, cerium, yttrium, tantalum, cobalt and titanium in mole ratio of (15-20): (8-10): (5-15): )13-19): (9-17): (16-23): (30-50). The coating of the electrode is difficult to fall off and the electrode is long in service life.

Description

technical field [0001] The invention relates to an electrode and its preparation method and application, in particular to an electrode capable of generating water hydroxyl groups and its preparation method and application. Background technique [0002] Food safety is related to the health and life safety of the general public, as well as to the healthy development of the economy and social stability. Food safety has become an important aspect to measure the quality of life of the people, the level of social management and the construction of the national legal system. At present, my country's food safety situation is not optimistic. Microbial pollution such as bacteria and viruses has existed for a long time, and chemical pollutants such as pesticides, hormones, and antibiotics have brought huge safety hazards to food. Foodborne diseases are still the biggest health problem facing human beings. killer. At the same time, the disinfection and sanitation of tableware closely re...
