DESCRIPTION:Speakers: Vera Pakharukova (Boreskov Institute of Catalysis)\n
 The elaboration of catalytic materials is related to abilities to effectiv
 ely probe nano-scale structures. There is significant drawback to common X
 RD methods addressed to well-crystallized materials\, since catalyst compo
 nents are often highly dispersed and present at low concentrations. The Pa
 ir Distribution Function (PDF) analysis based on operating with total scat
 tering data is one of the techniques of choice for structural characteriza
 tion of catalytic materials. Structural characterization of catalysts by t
 he PDF analysis has attracted particular interest in the last years\; the 
 method has already proven itself a powerful technique for the study on hig
 hly dispersed\, defect-rich and amorphous components of catalysts. The PDF
  describes local atomic structure of the material and provides structural 
 information in the form of a radial distribution function of inter-atomic 
 distances.\nIn the talk\, the PDFs calculated from synchrotron radiation d
 ata for different catalysts will be presented and types of structural info
 rmation extracted from the PDFs will be discussed. The possibilities of th
 e method to probe structure of supported nanoparticles in catalysts will b
 e shown for some examples: 1) mono- and bimetallic (Pt\, Rh)/γ-Al2O3 cata
 lysts for hydrocarbon oxidation\; 2) Ni/CeO2 catalyst for CO methanation 3
 ) MoS2/Al2O3 hydrotreating catalysts. The data will illustrate that the PD
 F analysis is effective tool for study on structural organization of the s
 upported catalysts and can be used to not only determine the nanoparticle 
 structure but also assess particle shape\, size of atomic ordering.\n\nhtt
