The advantages of titanium anodes in electrochemical reactions

In the electrochemical reaction, multi-component electrode is also a very important aspect of the study. Preparation of Ti / SnO2 Sb203 "Mn02 / Pb02 Mn02 anodes can be used as an example of multi-component electrode design.The main reason for the failure of titanium anodes is the diffusion of new eco-oxygen generated by the oxygen evolution reaction to the electrode surface, Generate non-conductive Ti02 film. In order to make the anode active, a layer of PbO2 MnO2 active layer is added on the surface of the electrode; in order to reduce the diffusion of new ecological oxygen to the titanium surface, a SnOzSb203 layer is added between the titanium electrode substrate and the active layer MnO2 intermediate layer In the treatment of phenol-containing wastewater, the anode has high electrocatalytic activity and electrochemical stability.

Titanium electrode is the key component of electrolysis water machine. The quality of the metal electrode directly affects the quality of the water machine. How to choose the electrode should be different according to the nature of the rational use of work in the field of water treatment metal electrodes must have the following basic requirements:

1. Has good electrical conductivity?

2. Strong corrosion resistance.

3 mechanical strength and processing performance.

4. Long working life.

5. Have good electrocatalytic properties.

In the field of water treatment, especially in the process of electrolysis of water, such as generating acid and alkaline ionized water, there are various strong oxidizing substances in the water, such as O3, H2O2, HCLO, etc., and the anode often commutates, therefore You must use special functional electrodes. Developed long-life electrodes suitable for water treatment ---- Titanium coated electrodes. This electrode is coated on pure titanium substrate electrocatalytic performance, strong oxidation resistance, good conductivity of the platinum group noble metal oxide, is an insoluble anode.

Titanium anode characteristics are:

1. Titanium has the proportion of light, good strength, corrosion resistance, superior performance characteristics, especially the performance of anti-wet chlorine is unmatched by other metal materials. For example: in the electrolysis of water with a trace amount of chloride ion, the stainless steel plate will soon pit corrosion, the electrode life shortened, while the titanium does not exist these problems.

2. In the coating as a result of adding a variety of platinum group precious metal, so the current efficiency, good conductivity, good electrocatalytic properties, oxidation resistance, long working life, energy conservation.

3 have a nice reverse performance.
