Graphene (G) and graphene oxides (GO) show exceptional physicochemical properties such as high electrical and thermal conductivity, extreme physical strength of carbon backbone, chemical tunability and nearly perfect transparency. They possess a high potential for applications in many scientific branches and in technology [1]. Fragmentation of G to carbon clusters was already studied [2, 3], but there is lack of information about GO ionization and fragmentation. Mass spectrometry (MS) of GO is still not sufficiently studied and described [2, 3]. In this work, the ionization of G and GO by laser desorption ionization MS equipped with a combination of quadrupole ion trap and time-of-flight analyzer was studied. The purpose was to understand processes of GO ionisation. This knowledge might help to understand the structure of GO. In conclusion, it was found that GO preparatives consist of many various sizes GO fragments forming a complex aggregate of single layers of GO “leaves” which are incorporating various GO molecules in between the layers (Fig. 1, arrows) and carrying varied number of oxo, hydroxyl or carboxyl groups. Some of GO fragments can be exfoliated using different solvents. In addition, carbon clusters Cn (n up to 350) were observed. The results will be discussed in detail.
