In the last few years, important efforts have been made to synthesize so‐called “multipore” zeolites, which contain channels of different dimensions within the same crystalline structure. This is a very attractive subject, since the presence of pores of different sizes would favor the preferential diffusion of reactants and products through those different channel systems, allowing unique catalytic activities for specific chemical processes. In this Review we describe the most attractive achievements in the rational synthesis of multipore zeolites, containing small to extra‐large pores, and the improvements reported for relevant chemical processes when these multipore zeolites have been used as catalysts. Molecular traffic control: Multipore zeolites contain channels of different sizes. They can be prepared in a planned manner and their channel structure offers advantages in shape‐ and size‐selective catalysis. The different rates molecules diffuse through the different channels is termed molecular traffic control.
