Investigation of temperature influence on the process of reduction of graphene oxide

Аңдатпа

The paper presents the results of influence different temperature on reducing graphene oxide. The influence of atmosphere pressure hydrogen gas at temperatures: 150 °C, 300 °C, 500 °C, 900 °C on the structure and composition of functionalized graphene was studied. The positions and ratio of Raman peaks of graphene oxide and thermally-reduced graphene are shown. Collected SEM images of graphene oxide are demonstrates layered structure, and the elemental composition of the thermally-reduced graphene at various temperatures was determined by using EDX spectroscopy. The obtained elemental analysis results are in good agreement with the data on the mass loss of thermally-reduced graphene, which is explained by the removal of functional groups.
