Iridium(IV) oxide recovery_ Iridium oxide recovery_ Precious metal catalyst recycling manufacturer

Iridium(IV) oxide is a chemical compound with the chemical formula IrO2. It is composed of iridium and oxygen elements, and is an oxide of iridium. Iridium is a valuable transition metal with high density, high melting point, and excellent corrosion resistance, making it widely used in many industrial and scientific fields.

There are several different ways to prepare Iridium(IV) oxide. Two common methods are described in detail below:

1. Thermal decomposition method: it is a commonly used method to prepare Iridium(IV) oxide. Firstly, dissolve a certain amount of iridium acid or ammonium iridium acid in an appropriate solvent to form a solution. Then, the solution is heated to a higher temperature, usually above 500 ℃, which will lead to the decomposition of iridium acid, releasing oxygen, and producing Iridium(IV) oxide. The reaction equation is as follows: 2IrO3 2IrO2+O2. Iridium(IV) oxide prepared by this method usually exists in the form of powder or particle, and can be used to prepare electrode materials, catalysts and other applications.

2. Hydrothermal method: Hydrothermal method is another method to prepare Iridium(IV) oxide. First, dissolve the iridium salt (such as iridium chloride) with an appropriate amount of sodium hydroxide or ammonium hydroxide in water to form a solution. Then, the solution is heated to high temperature and high pressure, usually reacting for a period of time at a pressure of over 200 ℃ and dozens of atmospheres. Under this condition, the iridium ion in the solution reacts with the hydroxide to form a precipitate, which is filtered, washed and dried to obtain pure Iridium(IV) oxide. The reaction equation is as follows: 2IrCl3+6NaOH 2IrO2+6NaCl+3H2O, Iridium(IV) oxide prepared by hydrothermal method often has higher purity and better crystal morphology, which is suitable for research and high-end application fields.
