METHOD FOR PRODUCING POROUS STRUCTURE

摘要

Disclosed is a method for producing a porous structure wherein a gelated material is produced from a raw material through a gelation reaction, and the gelated material is freeze-dried and then fired, thereby obtaining a porous structure. By such a method for producing a porous structure, there can be obtained a porous structure which has not only a large surface area, high porosity and high heat resistance but also water resistance, while being prevented from structural damage which may be caused when it is in contact with water. The method also contributes to safety and reduction of cost. This method for producing a porous structure can be suitably used as, for example, a method for producing a catalyst for processing exhaust gases.
