Abstract
Method of preparing zeolite single crystals with straight mesopores by applying a synthesis gel with zeolite precursor composition within the pore system and on the surface of a particulate matrix material template of carbon comprising the steps of:providing a templating material with a diameter of 2 to 50 nanometers and a length-to-diameter aspect ratio of at least 5,applying the zeolite precursor to the surface of the templating material using sequential impregnation,subjecting the precursor composition to crystallising conditions, andisolating porous single zeolite crystals with straight mesopores by removing the matrix template material.
