Реферат: Structural diagnostics of catalytic materials is related with an ability to study nano-scale structures. There is significant drawback with common XRD methods, since they probe well-crystallized materials. Alternative effective approaches take into account both the Bragg and diffuse scattering appeared in the XRD pattern. The structure of nanocrystalline phases can be determined using radial distribution function (RDF) of electron density or pair distribution function (PDF) method and direct modelling XRD patterns by the Debye Function Analysis (DFA). The possibilities of these methods to probe structure of catalytic materials are shown for some examples: 1) structural study of nanocrystalline γ-Ga2O3 oxide; 2) determination of local atomic structure of supported platinum in Pt/γ-Al2O3 catalysts.
