Long-life anode electrode material and preparation method thereof

Abstract

The invention provides a long-life anode electrode material and a preparation method thereof, and relates to the fields of new materials, new energy and environmental protection, in particular to the technical fields of electro-oxidative degradation of pollutants, electrically-driven membrane pollution-resistant electrodes, hydrogen production through water electrolysis and hydrogen fuel cell electrodes in the environmental protection industry. According to the main technical scheme, the anode electrode material comprises a metal substrate, a transition layer and a noble metal functional coating; the transition layer is deposited on the substrate; the noble metal functional coating is deposited on the transition layer; the transition layer is made of corrosion-resistant and high-potential-resistant metal oxide; and the noble metal functional coating is one or more metals selected from ruthenium, iridium, platinum, gold and silver, and a certain amount of one or more non-noble metals selected from tin, antimony, lead, manganese, nickel, silicon, cobalt and zinc are doped in the noble metal coating. The invention mainly aims at improving the binding force of the electrode coating and the metal substrate, reducing the content of noble metal, improving the efficiency of an electrode and prolonging the service life of the electrode.

Description

technical field

[0001] The invention relates to the technical fields of new materials, energy, and environmental protection, and relates to a long-life anode electrode material and a preparation method thereof, in particular to an electro-oxidation coating electrode in the environmental protection field, a pollution-resistant coating electrode in an electric drive membrane, a fuel cell, an electrolytic Preparation method of metal bipolar plate and diffusion layer coating in the field of hydrogen production from water. Background technique

[0002] Printing and dyeing, pharmaceutical, petroleum refining, coal chemical and other industries involve a large amount of organic refractory wastewater. Due to the high content of macromolecular organic matter, complex components, and difficult biochemical degradation, it has become a major industry problem. As a potential advanced oxidation technology, electro-oxidation technology has the advantages of simple equipment, non-differenti...
