Options
(a) zeolites
(b) enzymes

Zeolit is a most widely studied shape selective catalyst. Shape selectivity of zerolite depends upon pore strucutre of the catalyst, pore size generally varies between 260 pm to 740 pm. such catalyst are highly specific it is because molecules of only a particular size and shape enter these pores and get adsorbed .
