NON-SILICA MESOPOROUS OXIDE HAVING IMPROVED PORE STRUCTURE PERIODISM, METHOD OF PRODUCING THE MESOPOROUS OXIDE AND METHOD OF CRYSTALLIZING PORE WALL OF NON-SILICA MESOPOROUS OXIDE USING TEMPLATE TO BE FILLED IN PORES

摘要

A method for preparation for mesoporous oxide comprising a non silica oxide having a hexagonal pore structure periodicity and an average maximum pore length of from 2 nm to 5 nm, characterized by comprising blending 0.003 mol to 0.01 mol of TaCl5, NbCl5 or a mixture thereof and Al isopropoxide comprising 10 g of an aliphatic linear alcohol and 1 g of a template compound to prepare a mixture for forming a sol solution, adding 5 mol to 35 mol (based on the metal compounds) of water or an aqueous inorganic acid solution to the mixture followed by hydrolysis and polycondensation to give a sol solution, transferring the sol into an oxygen containing atmosphere followed by again at 40 °C to 100°C to form a gel, and then calcinating the gel in an oxygen containing atmosphere at 350 °C to 550 °C; and the mesoporous oxide obtained by the method.
