Describe some features of catalysis by zeolites.

Catalysis by zeolites is dependent on shape.Because zeolites are shape-selective catalysts.They are alumino silicates Which are microporous in nature.It has Honeycomb structure.That makes them shape selective.In zeolites, some si atoms are replaced by Al to form Al-O-Si network.

Reactants are very sensitive to the pore size of zeolites. Zeolites are used in petrochemical industry.Ex- ZSM-5 used to convert alcohol into gasoline.
