Bio-Based Graphene Sheet/Copolymer Composite as Supporting Material for Nanocatalysts towards Electrochemical Studies and Direct Alkaline Alcohol Fuel Cells

Figure 6

Effect of scan rate on Pt- and Pt-Pb-deposited Poly(AFCP-co-CP)-BGS catalysts for (i) 0.5 M methanol (a, b), (ii) 0.5 M ethylene glycol (c, d), and (iii) 0.5 M glycerol (e, f) in 0.5 M KOH solution. The inset graphs show the dependence of the anodic oxidation current with respect to the square root of scan rates.
