Atomic scale imaging and spectroscopic characterization of electrochemically reduced graphene oxide

High removal efficiency of dye pollutants by electron-Fenton process using a graphene based cathode

“…3a. The reduced peak area of GO was identified to be in the range of À0.15 to À0.65 V, from CV performed before the reduction step and this agree with that obtained by Dogan et al [42]. This peak disappeared almost totally after the reduction method applied (Fig.…”

Insight into the biosensing of graphene oxide: Present and future prospects

“…The main advantage of cyclic voltammetry as compared to the constant potential reduction is that it provides information about redox potential and the reversibility (Jiang et al, 2012) of the reaction. Typically, the electrochemical reduction of GO from aqueous suspension is carried out in the potential range of 0 -1.5 V. Scan rates in the range of 20 -100 mV s -1 have been reported Dogan et al, 2013). It has been noted that the cyclic voltammogram obtained from an aqueous suspension at a working electrode exhibits two cathodic current peaks Dogan et al, 2013).…”

Dogan et al, reported that the two peaks were in the range of -0.4 to -0.6 V (peak-I) and -0.6 V and -1.0 V (peak-II) with respect to the Ag/AgCl, 3 M NaCl electrode.…”

“…Dogan et al, reported that the two peaks were in the range of -0.4 to -0.6 V (peak-I) and -0.6 V and -1.0 V (peak-II) with respect to the Ag/AgCl, 3 M NaCl electrode. Some researchers Dogan et al, 2013) attributed the cathodic peak-II to the irreversible electrochemical reduction process of GO. The peak-I was ascribed to oxygen containing groups on the graphene plane that were too stable to be reduced using the cyclic voltammetric technique.…”

A highly active based graphene cathode for the electro-fenton reaction

“…In fact the higher current either time was, the more quantity of GO came and reduced on the surface of CF, forming an homogeneous graphene-layer which induced the acceleration of the electrochemical action as a consequence of the excellent electrical property of graphene. 19 Most of these groups were reduced at applied current density of À1.5 mA cm À2 in 10 min. 1f), and uncompleted reduction.…”
