【Abstract】 H2SO4-GIC was chemically synthesized in the concentrated sulfuric acid, in which hydrogen peroxide acted as oxidant. The present work studies the factors that influence the residual sulfur content and exfoliated volume, such as hydrogen peroxide concentration, the ratio of hydrogen peroxide and concentrated sulfuric acid, the pH value of the rinsing liquid, drying temperature and exfoliated temperature. The rational parameters for synthesizing low-sulfur GIC are obtained, and the intercalation mechanism is also discussed.更多还原
