Graphene nanosheets are delivered from easily available starting materials. We were synthesized chemically different types of graphene nanosheets, and used as electrocatalysts and their electrochemical properties were systematically characterized. We evaluated surface morphologies of graphene nanosheets via X-ray photoelectron spectra (XPS) and scanning electron microscopy (SEM). Also, we examine electrocatalytic activities using electrochemical impedance spectroscopy. Cyclic voltammetry, differential pulse voltammetry, and chronoamperometry were used for the electrochemical detection of serotonin which is an important neurotransmitter. A huge different results were observed with difference of graphene sheets due to reducing agent. Furthermore, the results obtained were compared with other graphene nanosheets. In all these experiments, graphene electrodes exhibited a better sensitivity, high signal-to-noise ratio, response time and possess higher stability than bare glassy carbon electrode.
