Abstract

Abstract

Graphite intercalation compounds (GICs) can be obtained when graphite is placed in strong oxidizing acids. Using this characteristic, we prepare liquid explosive by putting natural graphite in strong HNO₃ and mixing it with CH₃NO₂. Then we poured the mixture into a plastic container and placed the container at the center of a detonation reactor to ignite the explosive mixture. After the detonation, we collected and analyzed the soot by XRD, EDX, SEM, TEM, Raman spectroscopy, the specific surface area and porosity analyzer. Results indicate that the prepared grapheme possesses perfect crystal properties and exhibits a structure of thin sheets, with a specific surface area 9.16 times that of natural graphite and an average thickness of about 14.73 nm.
