X-ray and HRTEM structural studies of bulk nanoporous carbon materials produced from carbides

Abstract The data on the structural organization of bulk nanoporous carbon materials produced from a number of carbides by selective etching reaction with chlorine are reported. The studies were carried out by the techniques of small angle X-ray scattering, X-ray diffraction, and high resolution transmission electron microscopy. It is found that the typical nanopore size is 1–2 nm depending on the carbide precursor type. Differently organized nanodomains are identified in the highly disordered carbon skeleton of the materials.
