| description | Developing new materials or modifying the existing ones is an amply field studied in the world of research. Due to its outstanding physical and chemical properties, graphene is attractive material for new applications. The methodologies for obtaining graphene are diverse and have changed over time. Graphene oxide is a versatile form of graphene, due to the presence of oxygenated functional groups. Chemical oxidation of graphite and exfoliation by ultrasonic waves is one of the preferred methods to obtain graphene oxide; chemical oxidation time and the degassing effect in the ultrasonic bath are parameters that play an important role in the features and properties of graphene oxide. Thus, in this study, the conventional times used for the oxidation of graphite and degassing in an ultrasonic bath to obtain graphene oxide were modified. The structural changes in the carbon materials were evaluated based on their photocatalytic activity in the removal of an organic pollutant in water (removing up to 38% of phenol). The band gaps of the graphitic materials were obtained by UV-vis obtaining a value range of 1.5–4.7 eV and the structure and morphology of the carbon materials were characterized by infrared and Raman spectroscopies and transmission electron microscopy, respectively. |
