Known methods for producing porous carbonaceous materials require time-consuming polymerization 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 not only leads to sulfur contamination of the final material, but also corrosive and corrosive by-products and more complicated handling of the process. In order to avoid the disadvantages of the known methods while enabling the production of porous carbonaceous materials with large pore volumes, a) providing at least one carbon source and at least one amphiphilic species, b) obtaining a precursor material There is provided a method comprising combining at least a carbon source and an amphiphilic species, c) heating the precursor material to a temperature in the range of 300° C. to 600° C. for at least 15 minutes to obtain a porous carbonaceous material; The carbonaceous material is then cooled to form a porous carbonaceous material having a modem pore size, pore volume and backbone density. |
