Paper Abstract

Three precursors of graphite were employed to synthesise graphite oxides (GrO) that are now routinely obtained by the oxidation of a precursor graphite. These oxidation samples exhibit highly broadened D and G Raman bands which caused by the large amount of defects of graphene sheets. In addition, chemical oxidation results in the multiple peaks such as G*, D+D` and 2D`(in place of the conventional 2D band), which are activated by defects. The broad G band might also be deconvoluted in the actual G band and D` band, thereby attributing the broadening in G band. The band position and intensity ratio have also been demonstrated in the oxidized graphite.
