Adsorption and structural properties of inverse carbon replicas of two ordered siliceous P6mm and Ia3d mesostructures have been studied by nitrogen adsorption, powder X-ray diffraction, and transmission electron microscopy. These carbon replicas were prepared by filling the pores of SBA-15 and KIT-6 siliceous templates with various carbon precursors followed by carbonization and silica dissolution. Sucrose, furfuryl alcohol, acenaphthene, mesophase pitch, and petroleum pitch were used to obtain inverse carbon replicas of SBA-15 and KIT-6. While structural properties of the resulting ordered mesoporous carbons are mainly determined by the hard template used, their adsorption properties depend on the type of the carbon precursor.
通过氮气吸附、粉末X射线衍射和透射电子显微镜研究了两种有序硅质P6mm和Ia3d介观结构的反相碳复制品的吸附和结构性质。这些碳复制品是通过用各种碳前驱体填充SBA-15和KIT-6硅质模板的孔，然后进行碳化和二氧化硅溶解而制备的。使用蔗糖、糠醇、苊、中间相沥青和石油沥青来获得SBA-15和KIT-6的反相碳复制品。虽然所得有序介孔碳的结构性质主要由所用的硬模板决定，但其吸附性质取决于碳前驱体的类型。
