Abstract
A process for producing the ceramic porous body comprising the steps of (1) forming micelles in liquid by mixing 1 surfactant molecules, 2 surfactant molecules and given organic molecules, or 3 different kinds of surfactant molecules, (2) forming a precursor of a ceramic porous body having an organic-inorganic structure is formed 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 given organic molecules in the precursor of the ceramic porous body by photo-oxidation through irradiating vacuum ultraviolet light upon the precursor to leave an inorganic skeleton alone, and (4) thereby forming the ceramic porous body having nanometer-scale pores at a low temperature.
