Question

What is shape selective catalysis?

Answer 1

Shape selective catalysis

• A catalytic reaction that depends upon the pore structure of the catalyst and on the size of the reactant and the product molecules is called shape-selective catalysis.
• The most common example is catalysis by zeolites due to their honeycomb-like structure.

Example

• The reactions that occur in zeolites are influenced by the shape and size of reactant and product molecules.
• These reactions also depend upon the cavities and pores of the zeolites.
