Abstract

Heterogeneously nanostructured materials usually exhibit enhanced catalytic properties in comparison with each one of the constituent materials due to the synergistic effect among their different domains. In this chapter, we review recent development and our experimental investigations on Pt-containing nanomaterials with heterogeneous structures, e.g., core-shell, hollow interiors, stellated/dendritic morpholoies, dimeric, or composite construction, and their catalytic property toward direct methanol fuel cell reactions, including methanol oxidation reaction and oxygen reduction reaction in acidic conditions. A number of characterization techniques, including transmission electron microscopy (TEM), high-resolution TEM (HRTEM), high-angle annular dark-field scanning TEM (HAADF-STEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and energy-dispersive X-ray spectroscopy (EDX) are used to characterize the as-prepared heterogeneous nanomaterials, and to address the following critical issues: (i) the morphology and structure of the heterogeneous nanomaterials; (ii) the mechanism accounting for the morphological/structural formation of the final heterogeneous products; (iii) the influence of the coupling effect among different chemical components on the catalytic property of the heterogeneous nanomaterials.
