Abstract
Mesoporous high surface area and high crystallinity MO2 powders (TiO2, CeO2, ZrO2, and HfO2) were synthesized by a modified sol-gel method using laurylamine hydrochloride, metal alkoxide and acetylacetone. The prepared MO2 powders, characterized by XRD, nitrogen adsorption isotherm, SEM, TEM, and SAED, had crystalline size of about 5-15Â nm, specific surface area of 44-80Â m2/g, and a narrow pore size distribution with average pore diameter of about 3-6Â nm. This synthesis method provides a new simple route to fabricate nanostructured materials under mild conditions.
