摘要

The 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.
