Abstract
The present invention relates to a method for synthesizing mesoporous aluminosilicate or pure-silica molecular sieves with newly hierarchical morphologies by adding suitable amount of alcohol. There are hollow sphere, hollow sphere with a pillar in it and solid sphere by adjusting the Al,O,/SiO,and tetraethylorthosilicate/SiO,ratio. The wall of the micron-sized spherical structure consisted of well-ordered cylindrical pores of nanometer size. The dimensions and the morphologies of the mesoporous structure are adjustable by varying the reaction components as the water content, the silicon/surfactant ratio and the reaction and the hydrothermal temperature.
