| Abstract: | Sulfur-free exfoliated graphite at a low exfoliation temperature was prepared from graphite intercalation compounds (GICs) synthesized chemically with different consumption of insertion reagents and oxidants. The effects of their consumption on the synthesis of GICs and of exfoliation temperature on exfoliation volume were studied. The exfoliation volume was 350 ml/g at exfoliation temperature of 200 °C in the best process condition. These results revealed a marked development of the pores in Exfoliated graphite. |
