In this paper, we concern about CO tolerance of Platinum (Pt)/Graphene Nanosheets (GNS) catalysts dependence of pH. The aim of this research is to investigate relationship between CO tolerance and Pt particle size base on pH dependence and also supporting material effect to CO-tolerance. The research method is modified Hummers and impregnation method to synthesize GNS and Pt/GNS catalysts, respectively. The results show that electrocatalytic measurements of Pt/GNS catalyst prepared at pH = 1 has the highest CO tolerance (69.4 %) under 500 ppm CO level in the hydrogen oxidation reaction among pH = 6, 12.5 and Pt/CB commercial catalyst. It means pH dependence and GNS may be expected to enhance electrocatalytic activity (CO tolerance) of Pt. Furthermore, GNS is possible used as an anode catalyst of Polymer Electrolyte Fuel Cells (PEFCs).
