Title : New hierarchical cerium sulphate nanoflowers decorated reduced graphene oxide for electrochemical vitamin-c sensor
In this study, cerium sulphate nanoflowers (Ce2(SO4)3) decorated reduced graphene oxide (rGO) was synthesized through a rapid one pot solvothermal method. The crystal structure and morphology of the as-prepared nanohybrid composites were characterized using X-ray diffraction (XRD), field-emission-scanning electron microscopy (FESEM), Raman spectroscopy and Fourier Transform Infrared (FT-IR) spectroscopy. The electrochemical performance of the novel rGO/Ce2(SO4)3 biosensor was investigated via cyclic voltammetry. The biosensor was evaluated for Vitamin-C (Ascorbic Acid, AA) detection and exhibited a wide linear range of 100 to 600μl, and also efficient to sense a low detection limit.
