Abstract
In this study, an attempt has been made to synthesise the graphenelayers using electrochemical approach. This method is the cost effective and simple approach for the production of high-quality graphene. In this method graphite electrodes (both cathode and anode) were used instead of platinum, since the former is expensive. In particular, electrical properties of graphene were studied by varying the centrifuge parameters along with morphological examination. For characterisation, scanning electron microscope(SEM), UV spectroscopy, atomic force microscope (AFM), Fourier transmission infrared spectroscopy (FTIR) and X-ray diffraction (XRD) were utilised. Following are the observations; i) folded sheets of graphene were obtained, ii) anamorphous pattern at 2? = 26.6? was observed, iii) the absorption peak of graphene decreased at high wavelengths (266 nm), iv) the graphene peak was also confirmed by FTIR i.e. at 1655.5 (C=C) and v) thickness of flakes were found to be60nm by AFM. Moreover, further improvement in electrical conductivity of graphene layer is useful for dye-synthesized solar Cell (DSSC) applications which was synthesised in this research.
