Platinum coating Pure Titanium Dimensionally Stable Anode

Platinum coating Pure Titanium Dimensionally Stable Anode

Platinum-coated titanium electrode is a typical Dimensionally Stable Anode. It is a composite electrode constructed with a metallic titanium substrate as the base, upon which a thin layer of platinum (often not pure platinum but rather an alloy or mixture of platinum and other precious metals) serving as the active catalytic layer is applied onto its surface through specialized processes such as thermal decomposition or electroplating.

Platinum coating Pure Titanium Dimensionally Stable Anode

 

Core Structure:

 

Titanium Substrate: Serves as the backbone of the electrode, providing mechanical strength, electrical conductivity, and specific geometries (e.g., mesh, plate, rod). A key advantage of titanium lies in the formation of a dense passive film on its surface, which protects the substrate from corrosion during anodic polarization.

 

Platinum Coating: Acts as the active surface where electrochemical reactions occur, delivering exceptional electrocatalytic activity and chemical stability.


This product's surface is evenly coated in black and highly durable. It boasts low chlorine-evolution potential, a long service life, and high current efficiency. The DC current range is between 2000A/㎡ and 10000A/㎡. Its working temperature range is from 25℃ to 80℃. Different metal coatings are available, such as Ruthenium, Ruthenium plus Iridium, Ruthenium plus Iridium plus Tin, and Rare earth plus Ruthenium. The coating thickness can be between 2μm and 10μm depending on the amount of Ruthenium used, which ranges from 8g/㎡ to 35g/㎡. It's suitable for working in an environment of PH 0-14, in temperatures of up to 100℃, or even in seawater without being affected by corrosion.


Advantage

  • #
    Excellent Performance
    Electrocatalytic Activity: The surface platinum coating inherits the high catalytic activity of pure platinum electrodes, exhibiting low overpotentials for oxygen evolution reaction (OER), chlorine evolution reaction (CER), and hydrogen evolution reaction (HER), resulting in high reaction efficiency.
     
    Chemical Stability: The platinum layer is resistant to acids and corrosion, while the titanium substrate remains highly stable under anodic conditions due to its passive state. The entire electrode demonstrates an extended service life even in harsh environments.
  • #
    High Mechanical Strength and Light Weight
    The titanium metal substrate offers higher strength and greater resistance to deformation compared to solid platinum electrodes, while also being significantly lighter. This facilitates easier installation and assembly into large electrode arrays.
  • #
    Dimensional Stability
    When conventional solid metal electrodes are used as anodes, their surfaces may dissolve or undergo reconstruction. In contrast, the titanium substrate of the platinum-coated titanium electrode does not dissolve, and the firmly adhered platinum coating maintains its initial geometric profile and dimensions over prolonged periods, ensuring stable and consistent operation of the electrolyzer.

Manufacturing Process

Applications:

The chlor-alkali industry involves many different processes. Such processes include the diaphragm alkali legal system, the production of chlorine dioxide through electrowinning, acidic water electrolysis, electrochemical production of chlorine from sea water, sterilization of power plant circulating water alga with chlorine, electrowinning of metals in chloride systems, ionized water electrolysis, and electrodialysis.
 
 
These processes are all common components of the chlor-alkali industry and are regularly employed to produce different types of chlorine related products. Each process can be adjusted to meet specific needs in order to create higher quality and more efficiently produced chlorine related products.

The electrolyzer is fed a DC current from the rectifier and electrolyzes the diluted brine into sodium hypochlorite solution. Chlorine evolves at the anode surface, while hydrogen and hydroxide evolves at the cathode surface. The secondary reaction of chlorine, sodium and the hydroxyl ion nets sodium hypochlorite (chlorine bleach) at a 0.8% solution. Below 1%, hypo is classified as a non-hazardous chemical although still a very effective disinfectant. The only by-product, hydrogen, is safely vented into the atmosphere.

The UV-C ultraviolet light generated by the imported or high-quality domestically produced high-efficiency, high-intensity, and long-life UV-C ultraviolet light generating device is used to irradiate the flowing water. When the bacteria and viruses in the water are irradiated with a sufficient dose of UV-C ultraviolet light (wavelength 253.7nm), their cell DNA and cell structure are destroyed, and cell regeneration cannot proceed, thereby achieving the effect of water disinfection and purification. The ultraviolet light with a wavelength of 185nm can also decompose organic molecules in the water, produce hydroxyl free radicals, and oxidize organic molecules in the water into CO₂ and H₂O , and achieve the effect of removing TOC.
