Low-cost synthesis of high quality graphene oxide with large electrical and thermal conductivities

Electroanalytical Study of Fungicide Bixafen on Paste Electrode Based on the Thermally Reduced Graphene Oxide Synthesized in Air Conditions and its Determination in River Water Samples

“…Until now, different ways and techniques have been developed to obtain RGO [26,28]. Reduction of GO to produce RGO with a smaller amount of functional groups containing oxygen compared to GO and with features more similar to those of the pristine graphene [22,23,26] can be performed either by wet chemical methods [29] or thermal treatment in inert or reductive atmosphere [30].…”

However, the chemically reduced GO (CRGO) usually requires toxic and strongly reducing agents, e. g., hydrazine, sodium borohydride, which causes a strong agglomeration of the hydrophobic graphene flakes [31] with a significant number of impurities and structural disorders, which may have a strong impact on the quality and properties of RGO, including conductivity and electrochemical activity [28,30]. The thermal reduction of functional groups on the GO sheets is more advantageous compared to chemical reduction [32].…”
