Electrochemical properties of graphene nanosheets synthesized in microwave plasma torch discharge
Original language description
In the present work, 2-dimensional graphene nanosheets were synthesized, characterized and subsequently modified for gas sensor and electrochemical measurements. We used microwave plasma torch discharge (2.45 GHz) operating at atmospheric pressure conditions. Argon was used as the working gas and ethanol vapors, carried by argon, were used as precursor for carbon nanosheets synthesis. Characteristic high surface-to-volume ratio of prepared material, together with structural defects and various chemical groups on the surface serve as powerful combination for fast conductance changes upon adsorption. Therefore, prepared material consisting of graphene nanosheets was modified to perform different electrochemical measurements including gas sensing of ammonia and cyclic voltammetry characterization using several redox species. Our samples were analyzed by scanning electron microscopy, Raman spectroscopy and X-ray photoelectron spectroscopy to obtain an exact insight into the behavior of prepared sensors.
