Abstract

The present invention provides zeolite hollow spheres in which zeolite crystals grow to form a framework of macropore through a hydrothermal crystallization process using the hydrophilic surface of a carbon sphere as a hard template, wherein the zeolite framework is an ordered, porous crystalline zeolite material with a number of channels or pores interconnected, which has pore structures including mesopores and micropores. The zeolite hollow spheres of the present invention can be used for various purposes such as catalysts and adsorbents.
