Abstract

By the methods of x-ray diffraction and thermo-programmed desorption were investigated the effect of treatment with a pulsed discharge in the hydrogen environment on the of SCN (spherical carbonite saturated) sorption structure and characteristics of a carbon synthetic nanoporous sorbent SCN. It is shown that treatment with a pulsed gas discharge led to chemisorption of 0.4 wt. % of hydrogen, and also increased the sorption capacity of SCN during the physical sorption of hydrogen by a factor of 1.7. It can be assumed that the increase in the sorption capacity is due to changes in the equivalent pore size that result from the chemical interaction of the carbon atoms of the SCN with ionized during the discharge process hydrogen.
