Describe some features of catalysis by zeolites.

(N/A) Zeolites are alumino-silicates that are micro-porous in nature.
Zeolites have a honeycomb-like structure,which makes them shape-selective catalysts.
They have an extended $3D$ network of silicates in which some silicon atoms are replaced by aluminium atoms,giving them an $Al-O-Si$ framework.
The reactions taking place in zeolites are very sensitive to the pores and cavity size of the zeolites.
Zeolites are commonly used in the petrochemical industry.
