Iridium Carbon Recycling

Iridium carbon (Ir/C) is a composite material of iridium and carbon, which is often used in catalytic and electrochemical applications. It combines the high catalytic activity of iridium with the excellent electrical conductivity and stability of carbon, and exhibits excellent catalytic performance in many chemical reactions. Iridium carbon usually appears in the form of a supported catalyst, in which iridium metal particles are uniformly dispersed on the surface of a carbon material. It is widely used in fields such as hydrogenation reactions, oxygen reduction reactions, the production of hydrogen by electrolysis of water, and fuel cells. Iridium carbon is also used as a catalyst for certain organic synthesis reactions, especially in high temperature or highly corrosive environments. Iridium carbon's high stability and corrosion resistance make it an ideal catalytic material.

Below are some common types of iridium to carbon ratios:

1. Low-loaded iridium carbon (low iridium content): This type of iridium carbon usually contains a small amount of iridium (typically 1% to 5%) and accounts for the majority of the mass of the carbon-based material. This low-loaded iridium carbon is often used in applications that require high iridium catalytic activity but have limited iridium usage, such as electrocatalysis (e.g., oxygen reduction reaction) and fuel cells. The advantage of low-loaded iridium carbon is that it can reduce material costs while maintaining high catalytic efficiency.

2. High-loaded iridium carbon (high iridium content): High-loaded iridium carbon usually contains more than 10% iridium and is suitable for highly efficient catalytic reactions that require higher iridium metal catalytic activity. High-loading iridium carbon is commonly used in catalytic processes such as hydrogenation and hydrogenation reactions that require higher iridium metal surface activity. Although iridium is relatively expensive, high-loading iridium carbon can significantly improve reaction efficiency and product yield in certain demanding industrial catalysis.

3. Medium-loading iridium carbon (medium iridium content): This type of iridium carbon typically has an iridium content of about 5% to 10%, considering both catalytic efficiency and cost. Medium-loading iridium carbon is commonly used in a wide range of catalytic applications, including certain organic syntheses, oxygen reduction reaction (ORR), and hydrogen production by water electrolysis. It can provide better catalytic performance while using less iridium metal, making it suitable for medium-scale industrial and research-level applications.

4. Functionalized iridium carbon: In addition to pure iridium-loaded carbon composites, there are also some specially functionalized iridium carbons. These carbon-based materials may undergo certain surface modifications, such as nitrogen doping, oxidation, or other chemical functionalization treatments. These modifications improve the dispersion and catalytic performance of iridium, and enhance stability and poisoning resistance. Functionalized iridium carbon is often used in applications that require specific catalytic properties, such as complex organic reactions and environmental protection.

Waste iridium carbon is one of the raw materials for recycling iridium-containing precious metal catalysts. Iridium-containing precious metal catalysts also include the recovery of iridium oxide, recovery of chloroiridate, recovery of iridium acetate, recovery of iridium tetrachloride, recovery of iridium iodide, and recovery of ammonium chloroiridate.
