Topic : Graphene oxide – Synthesis, Characterization and assessment of its ability to detect Cr (VI)

Authors: S.Priya || B. Uma Devi,H.R. Uma

Abstract:Graphene engross researchers because of its fascinating electrical, thermal properties and mechanical stiffness. GO has been synthesized by methods like chemical vapour deposition, epitaxy method, sonication and by chemical treatment. In this work GO was synthesized by using modified Hummers method and characterised by UV, FT-IR, XRD and TEM analysis. UV- Vis studies showed peak at 300 nm is due to n- π* transition. XRD analysis showed that 2Ɵ value at 10o confirmed the formation of graphene oxide. TEM images clearly confirmed the layer structure in nanodimension. GO were used as a sensor for Chromium. The low concentration of Cr (VI) can be easily detected by GO. UV-Vis spectra were employed to study the sensing ability and the peak around 215 nm clearly revealed that GO formed complex with Cr through carboxylate ion. An attempt was made to employ GO to synthesize graphene using bioreductant.

Keywords: Hummer’s method, n- π* transition and Cr sensor
