Descripción general
Iridium oxide is a ceramic material with unique properties like long-term stability, sensitivity, electrochemical catalytic activity, and excellent biocompatibility. It can be formed from Ir metal by different methods like thermal decomposition, reactive sputtering, and electrochemical deposition. It is widely used in bio-electronic devices.
Aplicación
Iridium(IV) oxide can be used as:
- An indicator electrode in solid-state pH sensors.
- Coating material for stimulation electrodes.
- An anodic catalyst for oxygen evolution through a water-splitting reaction in a polymer electrolyte membrane (PEM) cell.
