A λ-MnO2 supported Pt nanocatalyst(5 wt.% Pt/λ-MnO2) was synthesized using a facile approach.X-ray diffraction(XRD), X-ray photoelectron spectroscopy(XPS), scanning electronic microscope(SEM), transmission electron microscopy(TEM), and energy disperse spectroscopy(EDS) were used for catalyst structure and morphology characterization, which showed that the metallic Pt particles were attached on a λ-MnO2 surface through the interaction between Pt and λ-MnO2.Cyclic voltammetry(CV) was used to test the catalytic activity of Pt/λ-MnO2 toward methanol oxidation, which showed that Pt/λ-MnO2 catalyst has much higher catalytic activity than baseline Pt/C catalyst.
