Method for preparation of porous carbonaceous material, porous carbonaceous material, and catalyst made of material
Known methods for preparing a porous carbonaceous material require lengthy polymerization and washing steps involving solvents or neutralizing agents. The use of a large quantity of pore formers leads to a lower carbon yield and higher costs, and use of sulphuric acid leads to sulphur contamination of the final material, and to corrosion and corrosive by-products and a more complicated handling of the method. In order to manufacture a porous carbonaceous material with a high pore volume and avoid the disadvantages of the known methods, a method is provide that comprise the steps of a) providing at least one carbon source and at least one amphiphilic species, b) combining at least the carbon source and the amphiphilic species to obtain a precursor material, c) heating the precursor material to a temperature in the range between 300 DEG C and 600 DEG C for at least 15 minutes so as to obtain a porous carbonaceous material, which is then cooled so as to form the porous carbonaceous material having a modal pore size, a pore volume and a skeleton density.
制备多孔碳质材料的已知方法需要长时间聚合和涉及溶剂或中和剂的洗涤步骤。大量成孔剂的使用导致较低碳收率和较高成本，并且硫酸的使用导致最终材料的硫污染，以及腐蚀和腐蚀性的副产物和该方法的更复杂的操作。为了能够制造具有高孔隙体积的多孔碳质材料和避免已知方法的缺点，提供一种方法，其包含步骤：a)提供至少一种碳源和至少一种两亲物类，b)合并至少碳源和两亲物类以获得前体材料，c)将所述前体材料加热到300℃至600℃的温度至少15分钟以获得多孔碳质材料，然后将其冷却以形成具有模态孔径和孔隙体积和骨架密度的多孔碳质材料。
