Abstract
Disclosed is a method for producing an inorganic porous body having precisely controlled macropores concurrently with mesopores of a narrow pore size distribution. The method comprises dissolving an amphiphilic substance as template component in an aqueous solution containing a sol-gel reaction catalyst, adding an inorganic low molecular weight compound having hydrolysable functional groups to the solution, forming a gel including a solvent-rich phase for the macropores, drying the gel to remove the solvent, and removing the template component by such means as thermal decomposition.
