阅读说明:本技术 制备多孔碳质材料的方法、多孔碳质材料和由所述材料制成的催化剂 (Method for preparing porous carbonaceous material, porous carbonaceous material and catalyst made of said material ) 是由 M·克洛斯 S·奥辛加 J·米肖-伯恩罗希纳 D·萨穆利斯 J·贝克尔 T·哈克 B·克 于 2020-03-19 设计创作,主要内容包括: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。(The known methods for preparing porous carbonaceous materials require long polymerization times and washing steps involving solvents or neutralizing agents. The use of large amounts of pore formers results in lower carbon yields and higher costs, and the use of sulfuric acid results in sulfur contamination of the final material, as well as corrosive and corrosive byproducts and more complex operation of the process. In order to be able to manufacture a porous carbonaceous material having a high pore volume and avoid the drawbacks of the known methods, a method is provided comprising 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 of from 300 ℃ to 600 ℃ for at least 15 minutes to obtain a porous carbonaceous material, which is then cooled to form a porous carbonaceous material having a modal pore size and a pore volume and a framework density.)
