Learn more about X‑ray Diffraction (XRD)
As part of Malvern Panalytical’s integrated catalyst characterization portfolio, X ray diffraction provides the definitive structural insight needed to understand how catalysts form, transform, and perform. Because catalytic activity and stability are tightly linked to crystalline phases, crystallite size, lattice strain, and metal–support interactions, XRD delivers the high resolution structural fingerprints that underpin rational catalyst design.
XRD enables researchers to identify active, support, and promoter phases; quantify crystallite dimensions; and monitor structural changes during synthesis, activation, reaction, and regeneration. With in situ and operando capabilities, these systems reveal how catalysts evolve under real processing conditions, capturing phase transitions, sintering behavior, and structural degradation mechanisms that directly impact activity, selectivity, and lifetime. This level of insight is essential for optimizing formulations, controlling metal dispersion, and ensuring long term durability.
Multi‑purpose diffractometer for phase analysis, crystallite size, residual stress, and in situ/operando studies. Determines active catalyst phases and monitors catalysis synthesis and degradation.
Comparison of Ni K-edge X-ray Absorption Spectroscopy (XAS) data collected on Empyrean and at a synchrotron. The XANES region (≈8300–8400 eV) provides insight into oxidation state and electronic structure; the EXAFS region (≈8400–8700 eV) captures the characteristic oscillations arising from the local atomic environment.
