Abstract

Nanocomposites of TiO2-reduced Graphene Oxide were synthesized with graphene oxide (GO) loadings of 4, 8, 12, and 16 mg via in situ sol-gel method. The raw material of graphene oxide was coconut shell charcoal which was processed using a modified Hummer’s method by dissolving the graphite into the acid mixture of H2SO4 and H3PO4. The rGO-TiO2 composites were characterized by X-ray Diffraction (XRD), Inductance, Capacitance & Resistance Meter (LCR-Meter), and UV-Vis. LCR-meter results revealed that the highest electrical conductivity of the sample is 5.37 × 10–6 Scm−1 with a GO composition of 4 mg. XRD analysis results show that the sample was having both anatase and rutile phases with anatase as the dominant phase. The photocatalytic activity of the sample was investigated using a photocatalytic reactor under UV exposure using methylene blue as a pollutant. Composite with GO loading 4 mg resulted in the best percentage of degradation reaching 81.37% in 15 min.
