“…The sheet-like structure of graphene with RuO 2 attached to its surface is confirmed by a higher magnification image. The aggregation of RuO 2 with graphene due to an increase in graphene weight percent results in an irregular flake-like morphology for the graphene structure, as seen in the magnified image 25 .…”

In this present work, graphene supported ruthenium oxide (rGO/RuO2) was synthesized by reflux method. Spectroscopic techniques were used to characterize the synthesized rGO/RuO2 NPs, including Fourier Transform Infrared (FT-IR), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), and Energy-Dispersive X-ray (EDAX). Synthesized rGO/RuO2 NPs that were prepared via reflux method at 150 °C for 3 hours showed a paper like structure with an average crystalline sizes of reduced graphene and rGO/RuO2 was found to be 14 and 10.3 nm. Therefore, the reflux synthesis method, as compared to more complex and time-consuming synthesis methods, can be used to easily and quickly produce high-quality, uniform-sized rGO/RuO2 NPs. The synthesized material has a successful application in electrochemical sensors, photocatalyst, antioxidant, hydrogen generation, used as catalyst in mines, minerals and fuels.

This study reports the extraction, characterization and development of reduced graphene oxide (rGO) doped silicon dioxide (SiO2) nanocomposite by simple reflux method. The nanocomposite was confirmed by using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and UV-Visible spectroscopy techniques. The photocatalysis of malachite green (MG) was carried out for rGO, SiO2 and SiO2/rGO nanocomposite shows higher MG degradation about 97% compared to rGO, SiO2 and follows 1 st order kinetics. The antioxidant action of SiO2/rGO nanocomposite was assessed using DPPH shows a more antioxidant activity (98 %) and lower IC50 about 488.35 mg/mL. From electrochemical, the specific capacitance (Csp) value of SiO2/rGO (114 F/g) was exhibits higher compared to rGO (75 F/g) and SiO2 (96 F/g) respectively. The CV and sensor detection of bee pollen and cow urine samples were performed using nickel mesh electrode in 1M KCl in the potential range -1 to 1 V. The SiO2/rGO was employed to analyze bee pollen and cow urine concentrations and the detection limits were found to be 0.260 mM and 0.413 mM respectively. The prepared electrode plays an important role for improving sensor detection of bee pollen and cow urine samples.
