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 TaCl<SUB>5</SUB>, NbCl<SUB>5 </SUB>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.
