Method for producing porous inorganic oxide |
| abstract |
PROBLEM TO BE SOLVED: To provide a porous material capable of precisely controlling a pore diameter to an arbitrary size and quickly and easily producing a porous inorganic oxide having a controlled pore diameter. Provided is a method for producing an inorganic oxide. SOLUTION: A hydrosol or hydrogel of a metal hydrate is synthesized by a pH swing in which the hydrosol or the hydrogel is alternately swung plural times or more between a precipitation pH region and a dissolution pH region, The resulting hydrosol or hydrogel of the metal hydrated oxide is dried, and then fired at a predetermined firing temperature to produce a porous inorganic oxide, the target pore diameter required for the porous inorganic oxide by the above pH swing. Control the approximate pore diameter smaller and closer to the target pore diameter, higher than the required firing temperature required for the porous inorganic oxide according to the difference between the value of the target pore diameter and the value of the approximate pore diameter By performing a high-temperature range firing operation of firing at the firing temperature set, This is a method for producing a porous inorganic oxide having pores controlled to a target pore diameter. |
