Looking beyond routine catalyst materials analysis

Nowadays, catalysts are found in many areas, from their use in the chemical industry, to the utilization in solar energy production, to everyday applications such as automotive catalysts. In the production of these materials, it is important to examine structure-performance relationships as well as identifying and understanding reaction mechanisms (i.e. the elementary reaction steps, intermediates, and active sites) under technologically relevant conditions. This requires an in-depth knowledge of the atomic structure on both the short- and long-range scales.

Multiple techniques within the realm of X-ray diffraction (XRD) can be utilized for catalytic materials. XRD provides information such as the identification and quantification of both crystalline and amorphous phases, particle and crystallite size, micro strain, thermal stability, particle size and shape, specific surface area and local atomic structure (i.e. short- and intermediate-range order).

In this webinar we will discuss the following methods with an emphasis on their application to catalytic materials:

  • X-ray powder diffraction
  • Non-ambient X-ray diffraction
  • Line profile analysis (LPA)
  • Small-angle X-ray scattering (SAXS)
  • Pair distribution function analysis (PDF)
