Abstract

The present invention provides an oxygen evolution electrode material containing FeOOH and a preparation method thereof. The oxygen evolution electrode material containing FeOOH is composed of metal nickel and FeOOH. The preparation method comprises the following steps of: preparing FeOOH by using a chemical precipitation method, a hydrothermal method, an electrodeposition method, a plasma chemical deposition method, a ferrous oxidation method or a forced hydrolysis method; and compounding metal nickel and FeOOH to obtain the oxygen evolution electrode. The invention has the advantages that: FeOOH is used as an oxygen evolution electrode and has excellent performance; FeOOH is inexpensive and widely available; the electrode is easy to prepare, can be prepared by a method for industrial preparation of DSA (dimensionally stable anode), and has strong practicality; and Fe is environmentally-friendly, thus reducing the environmental pollution caused by cobalt oxides.

Description

technical field

[0001] The invention relates to an oxygen evolution electrode material, specifically a nickel-based FeOOH electrode material. The invention also relates to a preparation method of an oxygen evolution electrode material containing FeOOH. Background technique

[0002] Hydrogen production by electrolysis of alkaline water is a common and mature method for producing hydrogen. Since this method does not require high equipment investment but consumes a lot of electricity, 80% of the operating cost in this method is concentrated on electric energy. Therefore, the energy conversion efficiency is low, the energy consumption of hydrogen production is high, and the cost is high. The wide application of water electrolysis hydrogen production technology is severely limited. The study found that in the process of water electrolysis for hydrogen production, a considerable part of energy is consumed in the polarization of the anode surface to generate oxygen evolution over...
