Iridium Tantalum Titanium Anode for Oxygen Evolution Reaction

Iridium Tantalum Titanium Anode for Oxygen Evolution Reaction

Mixed oxide catalysts have played an important role in oxygen evolution for various applications such as electroplating, electrowinning, electrosynthesis. The selection of anodic materials is a critical problem; dimensionally stable anodes (DSA) type anodes made with a titanium base metal coated with a platinum group metal catalyst are now widely used as anodes. These DSA anodes display better catalytic activity and durability towards oxygen evolution reaction (OER) than lead and graphite anodes. The IrO2-Ta2O5 is considered to be the best catalytic coating for OER in acidic electrolytes.

UTron manufacture iridium tantalum titanium anode for oxygen evolution reaction by the thermal decomposition method. The iridium tantalum coating layer is composed of fine oxide particles connected to each other to form a micro/mesoporous structure, the titanium substrate is protected from corrosion by the formation of a dense oxide layer at the interface between the porous oxide coating and titanium substrate. This iridium tantalum titanium anode has excellent catalytic properties for oxygen evolution in acidic solutions, and its long lifespan has been proven for applications in electro galvanizing, electrowinning, cathodic protection, and other applications.
