What are the advantages of titanium electrodes in electrochemical reactions?
Dec 26, 2023
In electrochemical reactions, the electrode surface area is accompanied by a heterogeneous catalytic reaction as charges move, which is similar to chemical catalysis. In a certain electrolyte, under the same overpotential, the electrode reaction rate and reaction type change due to different electrode matrix materials. This is collectively called electrocatalysis in electrochemistry. In electrocatalytic reactions, as electrocatalysts, different electrode materials can change the electrochemical reaction rate by orders of magnitude. Therefore, selecting appropriate electrode materials is an effective way to improve the efficiency of electrochemical catalytic reactions.
Titanium electrodes are key components in water electrolysis machines. The quality of metal electrodes directly affects the quality of the water purification machine. How to choose electrodes should be reasonably selected according to different working properties. In the field of water treatment, metal electrodes must have the following basic requirements:
1. Has good electrical conductivity.
2. Strong corrosion resistance.
3. Good mechanical strength and processing performance.
4. Long working life.
5. It has good electrocatalytic performance, etc.
After years of research, Di Noer Technology has developed a long-life electrode suitable for the field of water treatment - titanium metal coated electrode. This kind of electrode is an insoluble anode coated with platinum group noble metal oxides with high electrocatalytic performance, strong oxidation resistance and good conductivity on a pure titanium substrate.
The characteristics of this anode are:
1. Titanium has the characteristics of light specific gravity, good strength, corrosion resistance and good performance, especially its resistance to wet chlorine, which is unmatched by other metal materials. For example: when there is a trace amount of chloride ions in the electrolysis of water, the stainless steel plate will quickly undergo pitting corrosion, shortening the life of the electrode. However, titanium does not have these problems.
2. Due to the addition of a variety of platinum group precious metals in the coating, it has high current efficiency, good conductivity, good electrocatalytic performance, strong oxidation resistance, long working life, and energy saving.
3. It has good polarity reversal performance.
