In this study, we synthesize and evaluate a novel IrRuO_x/Graphene catalyst as anode catalyst for polymer electrolyte water electrolyzer. The IrRuO_x/Graphene catalyst was prepared by hydrothermal process and characterized by TEM, SEM-EDX, XRD, XPS and electrochemical methods. We successfully synthesized IrRuO_x nanoparticles catalyst dispersed on the graphene surface with controlled Ir/Ru ratio, which is proportional to the ratio of starting materials, Ir and Ru complexes, for the synthesis.
