Titanium anode electrode in the chemical reaction characteristics
In electrochemical reactions, the surface area of ??The electrode is accompanied by a heterogeneous catalytic reaction as the charge moves, and the reaction is similar to chemical catalysis. In a certain electrolyte, the same overpotential, the electrode reaction rate and the type of reaction due to changes in the electrode matrix material, which in electrochemistry collectively known as electrocatalysis. In the electrocatalytic reaction, as the electrocatalyst, different electrode materials can cause an electrochemical reaction rate to vary by orders of magnitude. Therefore, selecting the appropriate electrode material is an effective way to increase the efficiency of electrochemical catalytic reaction.
Electrochemical methods are used to treat difficult-to-degrade organic matter and have a great effect. It can transform non-biodegradable organic matter into biodegradable organic matter. Electrochemical conversion reaction rate of organic matter generally slow, so commonly used to increase the electrode overpotential, increase the electrode surface area, the selection of excellent electrode materials, and improve the electrode structure and other methods to be improved.
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, to form a 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.
