Detailed Solution

Shape-selective catalysis refers to the catalytic reaction in which the size of the molecules in the reactant and product molecules and the pore structure of the catalyst are both important factors.
Zeolites are microporous aluminosilicate that have a three-dimensional network of silicates in which some silicon atoms have been swapped out for aluminum atoms to create an Al-O-Si framework.They work well as catalysts that are shape-specific.
The honeycomb-like architecture of zeolites make them effective shape-selective catalysts.
