Abstract:
A process for producing a ceramic porous body comprising (1) forming micelles in a liquid by mixing {circle around (1)} surfactant molecules, {circle around (2)} surfactant molecules and organic molecules, or {circle around (3)} different kinds of surfactant molecules, (2) forming a precursor of a ceramic porous body having an organic-inorganic structure through mixing a ceramic material or a precursor of the ceramic material into the liquid containing the micelles, the precursor of the ceramic porous body comprising a template having the micelles arranged in a hexagonal, cubic or lamella form and the ceramic material or the ceramic material precursor adsorbed around the micelles, (3) removing the surfactant molecules or the surfactant molecules and the organic molecules in the precursor of the ceramic porous body by photo-oxidation solely through irradiating vacuum ultraviolet light upon the precursor of the ceramic porous body to leave an inorganic skeleton alone, and (4) thereby forming the ceramic porous body.
