Cyclic voltammetry in 0.1 M KNO3 was evaluated as an easy to use electrochemical methodology to reduce GO attached to the surface of screen-printed electrodes (SPEs). A cathodic peak related to the reduction of GO was identified, and the peak potential was correlated to the difficulty to reduce GO to electrochemically reduced graphene oxide (ERGO) depending on the functional groups present in the basal plane and in the edges of the original GO monolayers. Time-resolved UV–VIS absorption spectroelectrochemistry in near-normal reflection mode on a screen-printed electrode is used for the very first time as an in situ characterization technique for real-time monitoring unambiguously the electrochemical reduction of graphene oxide. projects CTQ2014-55583-R and CTQ2014-61914-EXP funded by Ministerio de Economía y Competitividad application/pdf eng Elsevier Electrochemistry Communications. 2016, V. 64, p. 65-68 https://doi.org/10.1016/j.elecom.2016.01.017 info:eu-repo/grantAgreement/MINECO/CTQ2014-55583-R info:eu-repo/grantAgreement/MINECO/CTQ2014-61914-EXP Attribution-NonCommercial-NoDerivatives 4.0 International http://creativecommons.org/licenses/by-nc-nd/4.0/ info:eu-repo/semantics/openAccess Graphene oxide Electrochemically reduced graphene oxide Screen-printed electrodes Cyclic voltammetry Raman spectroscopy UV–VIS spectroelectrochemistry Química analítica Chemistry, Analytic Aqueous UV–VIS spectroelectrochemical study of the voltammetric reduction of graphene oxide on screen-printed carbon electrodes info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion
