摘要：

The paper deals with the process of the subsequent intercalation of H2SO4 into CrO3-graphite intercalation compound (CrO3-GIC). The results of the X-ray diffraction measurements and cyclic potentiodynamic scanning show that in the course of the electrochemical intercalation the ternary CrO3-H2SO4-GIC of stage-1 structure is synthesized. CrO3-H2SO4-GIC appears very resistant against both the cathodic reduction and treatment with solvents. Deintercalation of CrO3-H2SO4-GIC results in the product of the better-ordered structure and surprisingly high concentration of sulfur. To approach the mechanism of the intercalation/deintercalation process the correlations between the current effects appearing on the potentiodynamic curves and the structural changes observed on the X-ray diffraction patterns are considered.
