▎ 摘　　要

A molybdenum disulfide (MoS2)/graphene nanoplatelet (GN) electrode was prepared by simple mixing and evaluated using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) with I-1/I-3(-) electrolyte as a redox mediator. The charge transfer resistance of the bare GN electrode without MoS2 was 1.4 x 10(3) cm(2), but with 70 wt% MoS2 became 53 Omega cm(2). Our results indicate that the catalytic ability improves when combining GNs with up to 70 wt% MoS2.
