Abstract
This paper presents original results of the analysis of the influence of preparation conditions on the formation of the porous structure of activated carbons derived from coconut shells and doped with nitrogen by combining ammoxidation with potassium hydroxide chemical activation. The clustering-based adsorption analysis process, the quenched solid density functional theory, and the non-local density functional theory methods were used in the analyses. Based on the obtained results, a significant effect of both the activation temperature and the mass ratio of precursor to chemical activator on the formation of the porous structure of the prepared activated carbons was observed. The materials with the best adsorption properties were the activated carbons prepared at 700 degrees C with mass ratios of raw material to chemical activator of 3 and 4. These materials were characterised not only by the highest development of the microporous structure, as indicated by the V-hA values i.e.: 1.563 cm & sup3;/g and 1.542 cm & sup3;/g, respectively, but also by the lowest degree of surface heterogeneity, as suggested by the surface heterogeneity parameter h = 1.
