What are the Main Types of Heterogeneous Catalysts?
Heterogeneous catalysts can be classified into three main types:
1. Metal Catalysts: Transition metals such as platinum, palladium, and nickel are commonly used due to their high catalytic activity. These metals can be used in their pure form or supported on materials like alumina or silica. 2. Metal Oxides: Oxides of metals such as titanium, vanadium, and chromium are often used in oxidation reactions. 3. Zeolites: These are crystalline aluminosilicates with a porous structure, which makes them highly effective in shape-selective catalysis.
