In order to improve the electrochemical characteristics of the electrode, a Mn-oxide/GNWs/SS310 system was deposited by magnetron sputtering (MS) from a target of MnO2. The morphology of GNWs electrode and the electrode decorated by Mn-oxide was evidenced by electronic microscopy. In addition, the samples were characterized electrochemically by cyclic voltammetry (CV) and galvanometric charge-discharge cycles (CDG). As a result, a specific capacitance of 0.21 mF/cm2 was obtained on the GNWs/SS310 electrode and 1.74 mF/cm2 on the MnO2/GNWs/SS310 electrode5 p.application/pdfengcc-by-nc-nd (c) Bossa, 2021http://creativecommons.org/licenses/by-nc-nd/3.0/es/GrafèDeposició química en fase vaporTreballs de fi de grauGrapheneChemical vapor depositionBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
