Fig. 7. (A) Cyclic voltammogram (CV) of electrocatalytic water splitting by a Ru-60 modified GC electrode where the black curve is the CV of the with uncompensated resistance (Ru), and the red curve is the CV with iR drop correction. (B) Chronoamperometric i–t profile for the same Ru-60 modified GC electrode. (C) CVs of electrocatalytic water splitting by Ru-60, Ru-CTAB, Ru-SDS and Ru-TX-100 modified GC electrodes. (D) The corresponding steady state polarization curves.
