As an essential part of numerous chemical processes, many catalysts contain valuable materials such as precious metals and nanomaterials. Catalyst dosing and activity tuning are essential for achieving the best product quality using minimum reaction time and process energy. XRD, XRF and NIR are essential tools for monitoring and controlling the fabrication and use of catalytic materials.

Typical applications include

  • In situ catalytic activity measurements
  • Phase analysis of heterogeneous catalysts
  • Nanoparticle size and shape analyses
  • Elemental composition of the catalysts during production and usage
  • Trace element analysis of doped catalysts
  • Catalyst poisoning
  • Fines and attrition determination

Characterization of catalysts and nanomaterials

Malvern Panalytical’s Empyrean XRD platform can be equipped with an Anton Paar high-pressure chamber for in situ activity measurements of catalysts, allowing catalyst optimization under the widest range of process conditions saving you time and money. Along with small-angle X-ray scattering (SAXS), this combination of platforms is perfectly suited for analyzing nanoparticle sizes and shapes. The pre-aligned fast interchangeable PreFIX modules can modify a typical XRD setup to a SAXS setup for nanomaterials analyses in approximately 5 minutes.

The CubiX³ is a robust XRD system and the fastest industrial diffractomer in its class for more routine analysis of your catalytic materials.

Zetium XRF systems provide accurate elemental analysis of both hetero- and homogenous catalysts. For example the determination of heavy metal concentrations by Zetium provides a cost-effective and efficient alternative to fire assay determination of precious metals.
