Which of the following statements about zeolites is true in the context of shape-selective catalysis?
Zeolites are a type of homogeneous catalyst
Zeolites have a random pore structure
Zeolites are used in catalytic converters in automobiles
Zeolites can selectively catalyze certain reactions based on their pore size and shape
Zeolites are a type of solid-state catalyst that have specific pore sizes and shapes that can be used to selectively catalyze certain reactions. The size and shape of the zeolite pores can control the access of reactants to the active sites on the surface of the catalyst, leading to selective reaction pathways. This technique is commonly used in the petrochemical industry to produce smaller hydrocarbon molecules for use as fuels and chemicals
