dc.description.abstract | Edge-selectively halogenated graphene nanoplatelets (XGnPs, X=C1, Br, and I) were prepared by the mechanochemically driven reaction between graphite and diatomic halogen molecules (Cl-2, Br-2 or 12). The contents of halogens (Cl, Br, and I) in XGnPs were 3.18, 1.77, and 0.66 at%, respectively, by X-ray photoelectron spectroscopy. The XGnPs as counter electrodes (CEs) showed remarkably enhanced electrocatalytic activities toward Co(bpy)(3)(3+) reduction reaction in dye-sensitized solar cells (DSSCs) with an excellent electrochemical stability. Amongst XGnPs, IGnP-CE demonstrated the lowest charge-transfer resistance (R-ct of 0.46 Omega cm(2) at the CE/electrolyte interface. This value is much lower than that of Pt-CE (0.81 Omega cm(2)). In addition, the DSSC with IGnP-CE had the highest fill factor (71.3%) and cell efficiency (10.31%), whereas those of DSSCs with Pt-CE were only 70.6% and 9.92%, respectively. (C) 2015 Elsevier Ltd.
