    • A process for producing the ceramic porous body comprising the steps of (1) forming micelles in liquid by mixing {circle around (1)} surfactant molecules, {circle around (2)} surfactant molecules and given 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 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.
    • 一种制造陶瓷多孔体的方法,包括以下步骤:(1)通过混合(圆周(1个表面活性剂分子,2个表面活性剂分子和给定的有机分子,或3个不同的 表面活性剂分子,(2)通过将陶瓷材料或陶瓷材料的前体混合到含有胶束的液体中形成具有有机 - 无机结构的陶瓷多孔体的前体,陶瓷多孔体的前体包含 具有以六边形,立方体或薄片形式布置的胶束和陶瓷材料或陶瓷材料前体吸附在胶束周围的模板,(3)去除表面活性剂分子或表面活性剂分子和陶瓷多孔的前体中的给定有机分子 通过对前体照射真空紫外光进行光氧化,单独留下无机骨架,(4)由此形成 该陶瓷多孔体在低温下具有纳米尺度的孔。
