(a) Optical microscopic image and schematic section view of HOPG surface with a graphene-layered structure. Numerous graphite step centers and edges are formed during mechanical exfoliation. (b) G and D peak Raman spectra on the step center of graphite as a function of reaction time in 1.25 × 10−7 M Cp*RuL3PF6 solution. (c) G and D peak Raman spectra and (d) D/G peak intensity ratio on step edge of graphite as a function of reaction time in 1.25 × 10−7 M of Cp*RuL3PF6 solution. Inset of panel (c) shows enlarged D peak region of Raman spectra.
