- Аннотация: The formation of binary graphite intercalation compounds ( GICs) with nitric and sulfuric acids in the presence of a strong oxidant has been studied by x- ray diffraction and potentiometry in a wide range of acid concentrations. The redox potential of the oxidizing solution and the intercalation ability of the acid are shown to influence the stage number ( the number of graphite layers between two successive intercalate layers) of the forming GIC and the concentration ranges of GIC formation. The (E-H2) - H-0 ( redox potential of the oxidizing solution - Hammett function of the acid) stability fields of graphite nitrate and graphite bisulfate are presented. Our results are the first to demonstrate that KMnO4 extends the concentration ranges of GIC formation and reduces the threshold acid concentration for the synthesis of binary GICs ( to 40%).
