Реферат: In the present work, the possibility of forming graphite intercalation compounds by treatment of partially graphitized diamond crystals by sulfuric acid in the presence of an oxidizer was demonstrated. The elemental mapping of the acid-treated crystals showed that sulfur and oxygen were localized in the graphite phase, which formed around the vertices and edges of the crystals. Mass-spectrometry was used to study the stages of thermal decomposition of the synthesized intercalation compound. When the intercalation compound decomposed, the graphitic layers were oxidized by sulfuric acid and SO2 evolved with the maximum on the evolution curve at 250 ℃. The adsorbed water and functional groups present on the graphite surface were eliminated at lower temperatures. The proposed synthesis method can be used for obtaining intercalated graphite-modified diamond, which is promising for applications in electronic devices.
