THE METHOD OF PREPARATION OF NANOPOROUS CARBON MATERIALS

摘要

The subject of the present invention is a method of preparation of nanoporous carbon materials via mixing a carbon material with silica used as a matrix, drying the obtained material and its calcination. The present invention is characterised in that molasses in the mass ratio to silica in the range from 0.2 to 2 is used as the source of carbon. The essential feature of the present method is that cane or beet molasses is used. Advantageous effects are obtained by conducting calcination at the temperature range of 300-1200°C. After calcination, the silica matrix is removed using 35% by mass hydrofluoric acid. Then, the material is washed with water until neutral reaction is obtained and the material is later dried.
