Nano-IrO₂ (iridium dioxide) has important application potential as an anode catalyst in hydrogen electrolyzers, especially in proton exchange membrane (PEM) water electrolysis hydrogen production technology. The following are the main characteristics and application advantages of nano-IrO₂ as an anode catalyst:
1. High catalytic activity
IrO₂ is an efficient oxygen evolution reaction (OER) catalyst that can promote the decomposition of water at low overpotential to generate oxygen and protons.
Nano-scale IrO₂ has a larger specific surface area and more active sites, which significantly improves the catalytic efficiency.
2. Excellent stability
IrO₂ shows good chemical stability in acidic environments and is suitable for the strong acidic working conditions of PEM electrolyzers.
The nanostructure can further enhance the mechanical stability and durability of the material and extend the service life of the catalyst.
3. Electrical conductivity
IrO₂ has good electrical conductivity, can effectively transfer electrons, and reduce energy loss during electrolysis.
4. Reduce the amount of iridium used
Iridium (Ir) is a rare and expensive precious metal. Nano-sizing can significantly reduce the amount of IrO₂ while maintaining high catalytic performance, thereby reducing catalyst costs.
