Despite their advantages, zeolites face certain challenges:
1. Deactivation: Zeolites can be deactivated by coking, where carbon deposits block the pores and active sites. 2. Limited Pore Size: The small pore size can restrict the diffusion of bulky molecules, limiting their application in some catalytic processes. 3. Cost: The synthesis of advanced zeolite catalysts can be expensive, which may limit their widespread adoption.
