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 of producing a mesoporous oxide comprising a non-silica oxide having a hexagonal pore structure periodism and an average maximum pore length of from 2 to 5 nm, characterized by comprising blending 0.003 to 0.01 mol of TaCl5, NbCl5 or a mixture thereof and Al isopropoxide with a solution 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 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 aging at 40 to 100°C to form a gel, and then baking the gel in an oxygen-containing atmosphere at 350 to 550°C; and the mesoporous oxide obtained by the method.
