Metal Nanocatalysts

  • Chapter
  • First Online:
XAFS Techniques for Catalysts, Nanomaterials, and Surfaces

Abstract

Metal catalysts in nanometer size range are under worldwide investigations due to their fascinating electronic and atomic strucutures which play essential roles in tuning catalytic properties of metal catalysts. Owing to intrinsically high disorder, asymmetric bond distributions, heterogeneity in particle sizes and compositions, as well as strong coupling between the structural properties and environment, nanosized metal catalysts present a number of challenging problems in EXAFS analysis for determining the size, structure, shape, support orientation of nanocatalysts in real time and in reaction conditions. In this chapter we review methods of EXAFS analysis developed in the last two decades for structural characterization of mono- and bi-metallic nanocatalysts.
