    • Porous materials having a metal oxide skeleton are taught that have various water vapor adsorption capacities defined by the amount of adsorbed water vapor at a specific relative vapor pressure in a water vapor adsorption isotherm. A preferred porous material has a water vapor adsorption capacity that is less than or equal to 0.1 g/g at a relative vapor pressure of 10%, and greater than or equal to 0.2 g/g at a relative vapor pressure of 28%. Methods of making such porous materials are also taught. A preferred method for forming a porous material includes condensing a skeleton starting material for the porous material, in the presence of a surfactant, in a solution which has a concentration of the skeleton starting material in the solution that is less than or equal to 0.4 mol/L and a molar ratio of the surfactant to the skeleton starting material that is greater than or equal to 0.05 and less than or equal to 50, to form a condensate and removing the surfactant from the condensate.
    • 教导了具有金属氧化物骨架的多孔材料,其具有由在水蒸气吸附等温线中的特定相对蒸汽压下的吸附水蒸汽量定义的各种水蒸气吸附容量。 优选的多孔材料在相对蒸汽压力为28%的相对蒸汽压力为10%,大于或等于0.2g / g时具有小于或等于0.1g / g的水蒸气吸附能力。 还教导制造这种多孔材料的方法。 用于形成多孔材料的优选方法包括在表面活性剂存在下将多孔材料的骨架原料冷凝在溶液中的骨架原料浓度小于或等于0.4mol / L,表面活性剂与骨架原料的摩尔比大于或等于0.05且小于或等于50,以形成冷凝物并从冷凝物中除去表面活性剂。
