Patent ID: 7326398

Claim:
A method for preparation of mesoporous oxide composed of non-silica mesoporous oxide whose fine pore structure periodicity is hexagonal array structure, average maximum length of fine pores is from 2 nm to 50 nm and the wall which forms said fine pores is composed of non-silica oxide selected from the group consisting of Ta oxide, Nb oxide, mixed oxide of Ta and Nb and Al oxide comprising; preparing a mixture for forming sol solution by blending 0.003 mol-0.01 mol of either TaCl 5 , NbCl 5 , a mixture of TaCl 5 and NbCl 5 , or Al isopropoxide into a solution composed of 10 g of aliphatic normal alcohol and 1 g of template compound, adding water or an aqueous solution of inorganic acid in an amount that is 5-35 times the mol concentration of the metal compound present in the mixture, hydrolyzing and polycondensing to form sol solution, transporting said sol to the environment where oxygen is existing to form gel by maturing at 40° C.-100° C. and calcinating said gel in the environment where oxygen is existing at 350° C.-550° C.
