Platinum-coated titanium anodes: electrochemical materials with excellent performance

In the field of electrochemistry, platinum-coated titanium anodes are a key material that has attracted much attention due to its unique properties and wide range of applications. Let's have an in-depth discussion on the characteristics, preparation method and application value of this advanced material in various fields.

I. Principle and characteristics of platinum-coated titanium anode

Platinum-coated titanium anode, as the name suggests, is a functional electrode coated with a layer of platinum on the surface of titanium metal substrate. Titanium becomes an ideal electrode substrate material due to its good corrosion resistance and mechanical strength, while platinum provides efficient electrochemical reaction performance for the electrode due to its excellent catalytic activity and stability.

The operating principle is based on the redox reaction in electrochemistry. When an external electric field is applied, the platinum coating acts as a catalyst that significantly reduces the activation energy of the reaction and promotes the transfer of electrons and the conversion of substances, thus realizing highly efficient electrolysis, electrosynthesis and other processes.

This anode has a number of excellent properties. First, the platinum coating endows the titanium anode with extremely high catalytic activity, enabling rapid and efficient initiation of electrochemical reactions in a variety of electrolyte solutions. Secondly, the corrosion resistance of titanium matrix makes the electrode still work stably in harsh environments such as strong acid and alkali, which greatly extends the service life of the electrode. In addition, platinum-coated titanium anode also has low oxygen precipitation overpotential and chlorine precipitation overpotential, which can effectively reduce the energy consumption in the electrolysis process.

II. Preparation method of platinum-coated titanium anode

At present, the methods of preparing platinum coated titanium anode mainly include painting method, electroplating method, thermal decomposition method, magnetron sputtering method, etc. The electroplating method is a traditional method of preparing platinum coated titanium anode.

Electroplating method is a traditional preparation method, through electroplating on the surface of titanium substrate, platinum ions are reduced and deposited on the substrate to form a coating. The method is simple and low cost, but the combination and uniformity of the coating is relatively poor.

Thermal decomposition method is the platinum-containing organometallic compounds coated on the surface of the titanium substrate, and then heated to make the organometallic compounds decomposition, so as to form a platinum coating on the substrate. The coating prepared by this method has a strong binding force and good uniformity, but the process is relatively complex and costly.

Magnetron sputtering method is the use of magnetron sputtering equipment, in a high-vacuum environment, the platinum target sputtering to the surface of the titanium substrate to form a coating. The coating prepared by this method has high purity, dense and uniform film layer, but the equipment investment is larger and the production cost is higher.

All the titanium anodes of our company adopt manual coating method, each product is repeatedly coated with standard content, and we will also carry out all the quality tests on the products before shipment to eliminate the inferior products with scratches and cracks. To ensure product quality, which also makes our products are favored by the majority of customers and re-purchase.
