Abstract

The invention discloses an electrolysis anode plate and a preparation method and application thereof. The preparation method comprises the steps of uniformly coating a substrate with an intermediate layer coating solution; and then, uniformly electroplating an intermediate layer of the substrate with an electroplating solution, and carrying out drying to obtain the electrolysis anode plate. The surface electrochemical activity surface area of a plating of the prepared electrolysis anode plate is larger, so that the electrolysis anode plate has more chemical reactivity sites during the utilization process, has extremely high electrochemical reactivity, facilitates decomposition of catalytic water, and is applied to the aspects of electrolysis dehydration, ectrolysed water and electrotransformation gas.

Description

technical field

[0001] The invention relates to the fields of material chemistry and environmental electrochemistry, in particular to an electrolytic anode plate and its preparation method and application. Background technique

[0002] Titanium-based metal oxide coated electrode (DSA) has shown excellent anode performance since its inception, and has been widely used in the electrolysis industry soon. Titanium has a high melting point, light weight and high strength, and plays an important role in aerospace and chemical industries. Traditional lead-based alloy electrodes and graphite electrodes have high oxygen evolution potential and high energy consumption. Studies have shown that some metal oxides, especially transition metal oxides, have high electrocatalytic activity and low oxygen evolution potential. Compared with the traditional lead-based alloy electrode and graphite electrode, the titanium-based electrode coated with metal oxide has the advantages of stable anode...
