dc.description.abstractThe influence of oxidation states on electrocatalytic abilities for I-3(-) reduction is discussed for reduced graphene oxide (rGO), which is a promising catalyst of counter electrodes for dye-sensitized solar cells (DSSCs). The oxidation states of rGO can be controlled via a photothermal reduction process by varying exposure times. The results reveal that the rGO with lower oxidation state shows smaller charge transfer resistance at the electrode/electrolyte interface and better electrocatalytic ability attributed to higher standard heterogeneous rate constant (k(0)) and reasonable electrochemical surface area (A(e)) for I-3(-) reduction, both are quantitatively determined by a rotating disk electrode system using the Koutecky-Levich equation.en_US
