Structural features of nitrogen-containing nanoporous carbon materials’ formation

Abstract

With the methods of small-angle X-ray scattering and nitrogen sorption under the temperature of –196 °С we have investigated structure of nanoporous carbon, which is got by carbonization of vegetable product. Also this way we have investigated influence of chemical and thermal activation to it. It is detected, that carbon material, that have been nitrogenized under the temperature of 450 °C indicates maximum specific surface 1340 m2/g. With the Guinier  approximation there have been estimated functions for distribution of nanoporous by electron radius of inertia f(Rg), determined average dimensions on nanoporous, equal 0.9 nm.
