Introductions
Precious metal catalysts are noble metals widely used in the chemical industry owing to their ability to speed up the chemical process. Gold, palladium, platinum, rhodium, and silver are some of the examples of precious metals. Precious metal catalysts are those which consist of highly dispersed nano-scale precious metal particles supported on a high surface area such as carbon, silica, and alumina. These catalysts have several applications in a variety of industries. Each precious metal catalyst has unique characteristics. These catalysts are primarily used for organic synthesis reactions. Factors such as growing demand from end-use sectors, environmental concerns and their legal implications are driving the market growth.
Properties of precious metal catalysts
1.High activity and selectivity of precious metals in catalysis
Precious metal catalysts consist of highly dispersed nano-scale precious metal particles on supports with high surface area such as carbon, silica, and alumina. The nano scale metal particles easily adsorb hydrogen and oxygen in the atmosphere. The hydrogen or oxygen is very active due to its dissociative adsorption through d-electron of out of shell of precious metal atoms.
2.Stability
Precious metals are stable. They do not easily form oxides by oxidation. The oxides of precious metals are, on the other hand, relatively not stable. Precious metals do not easily dissolve in acid or alkaline solution. Because of high thermal stability, precious metal catalyst has been used as automotive exhaust gas purification catalysts.
