Question

Which one of the following is a shape selective catalyst?

• A. $V_2{O}_3$
• B. $C{r}_2{O}_3$
• C. $ZSM-5$
• D. None of the above

Answer 1

The correct option is C $ZSM-5$

The catalytic reaction that depends upon the structure of pores of the catalyst and the size of the reactant and product molecules is called shape/selective catalysis. Zeolites are good shape selective catalysts because of their honeycomb structure. ZSM-5 is a zeolite and shape selective catalyst .
