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.
