iridium(+4) cation - Introduction
iridium(iv) oxide hydrate(iridium(IV) oxide hydrate) is an inorganic compound with the chemical formula IrO2 · xH2O (where x represents the number of hydrates). The following is a description of its nature, use, preparation and safety information:
1. Nature:
iridium(iv) oxide hydrate is a black powdery solid with high chemical and thermal stability. It is a material with semiconducting properties and is insoluble in water and most common organic solvents at room temperature. It has high density and good electrical conductivity.
2. Use:
iridium(iv) oxide hydrate has many important application areas, including:
-Catalyst: Due to its excellent oxidation performance and electrochemical activity, it can be used as a catalyst, such as water decomposition, water electrolysis, fuel cells, etc.
-Electrochemical devices: iridium(iv) oxide hydrate is widely used in the field of electrochemical energy storage and sensors.
-Electrode material: It can be used as the positive electrode of batteries and the electrode material of supercapacitors.
-Water treatment: It can be used for electrochemical oxidation and electrolysis in the water treatment process.
3. Preparation method:
iridium(iv) oxide hydrate can be prepared by reacting iridium acid and ammonium salt under appropriate conditions. A common method of preparation is the reaction of iridium (III) chloride with hydrogen peroxide, followed by hydrolysis to give iridium(iv) oxide hydrate.
4. Safety Information:
Since iridium(iv) oxide hydrate is a compound containing iridium, and iridium is a rare and expensive metal, it is not a common industrial material. Use only in the laboratory or in a specific research environment. Use should follow laboratory safety practices and avoid direct contact with skin and inhalation of dust. For any chemical, it is recommended to read the safety data sheet carefully and take appropriate precautions before use.
