Catalysis is a chemical reaction with participation of a catalyst.

Catalysts are noted for lowering the activation energy of a reaction.

The use of catalysts allows to carry out reactions even under conditions (especially temperature) which without catalysts would be extremely slow. Though catalysts participate in a reaction, they are not consumed. They do not influence the thermodynamic equilibrium because the back reaction is also catalyzed. Catalysts minimize the time for reaching an equilibrium.

Principally, one can differentiate between three types of catalysts:

1. Heterogeneous catalysts

2. Homogeneous catalysts

3. Biocatalysts
