Synchrotron X-ray diffraction (XRD) is a powerful analytical technique that leverages the intense and highly collimated X-ray beams produced by synchrotron radiation sources. These X-rays are used to probe the structural characteristics of materials at the atomic and molecular levels. In the context of catalysis, synchrotron XRD can provide detailed insights into the structure of catalysts under various conditions, including in situ and operando environments.
