1.Product Description
The iridium-tantalum mixed oxide-coated titanium anode is an advanced electrochemical electrode material. Its core principle is to reduce the overpotential of the oxygen evolution reaction (OER) through the catalytic action of a precious metal oxide coating. This anode utilizes a titanium substrate as a conductive base, coated with a mixed oxide active layer composed of iridium (Ir) and tantalum (Ta).
2.Core Advantages
-Symmetrical Effect: Iridium and tantalum oxides form a solid solution structure, with iridium dioxide providing high catalytic activity and tantalum pentoxide enhancing coating stability and corrosion resistance.
- Electrochemical Performance: The ultra-low overpotential helps reduce cell voltage at high current densities, saving energy.
-In strong acidic media (such as 1M sulfuric acid), the coating exhibits excellent electrocatalytic activity. Even at extremely high current densities, the overpotential remains extremely low, significantly improving electrolysis efficiency.
-High Stability: In harsh acidic environments, the coating's durability far exceeds that of conventional materials, significantly extending its service life and demonstrating exceptional chemical stability and corrosion resistance.
