摘要: This paper presents results of the analysis impact activation temperature and mass ratio activator to carbonized precursor R on porous structure nitrogen-doped activated carbons derived from lotus leaves by carbonization chemical with sodium amide NaNH2. The analyses were carried out via new numerical clustering-based adsorption (LBET) method applied nitrogen isotherms at −195.8 °C. On basis obtained it was shown that amount activator, as compared temperatures, has a significantly greater influence formation carbons. As in study, optimum values parameters are for = 2. At 3, significant decrease observed, indicating uncontrolled wall firing between adjacent micropores. conducted confirmed validity method, turned prepared characterized high share micropores degree surface heterogeneity most samples studied, which may, some extent, undermine reliability using classical methods assume only homogeneous pore structure.
