With polystyrene latex spheres self-assembled on ITO glass as templates, highly ordered two-dimensional (2D) Pt nanoparticles (PtNPs) were prepared by electrochemical deposition. The morphology and element composition of PtNPs were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The electrocatalytic properties of PtNPs/ITO and Sn underpotential deposition (UPD) modified PtNPs/ITO for methanol oxidation has been investigated by cyclic voltammetry (CV) and chronoamperometry (CA). The excellent electrocatalytic activity can be observed for these catalytic systems. (C) 2008 Elsevier B.V. All rights reserved.
