Types of Catalyst or Catalysis

Catalysis can be divided into two main types :

• Heterogeneous Catalysis
• Homogeneous Catalysis

Heterogeneous catalysis:

Heterogeneous implies different. Heterogeneous catalysis has the catalyst in a different phase from the reactants.

Homogeneous catalysis:

Homogeneous implies the same. Homogeneous catalysis has the catalyst in the same phase as the reactants.

Besides, catalysis may be divided into some other types:

• Positive Catalysis
• Negative Catalysis / Inhibition.
• Auto Catalysis
