We report the synthesis and characterization of a series of hierarchical porous zeolite single crystal materials with a range of porosities made available by carbon-templating using differently-sized carbon particles as templates for the additional non-micropore porosity. The materials were prepared by adsorption of the required zeolite synthesis gel components onto various commercially available carbon black powders followed by crystallization of the zeolite crystals in the presence of the inert carbon matrix and subsequent removal of the carbon particles embedded in the zeolite crystals by combustion. It is shown that the additional porosity of the hierarchical zeolites can be tailored by encapsulation of the differently-sized carbon particles during crystallization.
