Abstract

SKS active carbon, prepared by dehydrogenation of the polystyrene–divinylbenzene copolymer, as a model sample of highly amorphous carbons, has been examined by scanning electron microscopy, transmission electron microscopy, and energy dispersive X-ray methods, indicating a nanostructural nonperiodic character of the resulting product. No crystalline-like particles are experimentally found in the bulk. The PSDVB copolymer dehydrogenation has been quantum chemically (QC) simulated to describe the interconnecting amorphous phase. A set of clusters with a different degree of carbonization has been QC evaluated. The first level model of the amorphous active carbon has been proposed.
