<p>In a production method disclosed in the present invention, the hydrolysis and polymerization of a silicon compound having a hydrolysable functional group by a sol-gel method and the phase separation of a solution system containing the compound are allowed to proceed in the system to form a gel which is composed of a skeletal phase containing a polymer of the compound at a high concentration and having fine pores formed therein and a solution phase containing a solvent of the system at a high concentration and which has a co-continuous structure composed of the two phases, and subsequently the gel is dried. In this manner, a macro-porous monolith having a (meso pore)-(macro pore) layered porous structure in which the skeletal phase serves as a skeleton, each of the fine pores is a meso pore, and the solution phase serves as a macro pore can be produced. In the method, the silicon compound is a hydrogenated silicon compound having a Si-H bond in the molecule. On the surface of the skeleton and in the inside of the meso pore in the macro-porous monolith, hydrogen sites each derived from the Si-H bond are distributed.</p> |
