X-ray pulse experiments typically involve synchronizing the X-ray pulses with the catalytic reaction. This synchronization allows researchers to capture snapshots of the catalyst at different stages of the reaction, providing a time-resolved picture of the process. Common techniques include:
- Pump-Probe Experiments: A pump pulse initiates the reaction, while a probe pulse captures the state of the catalyst at various time intervals. - Time-Resolved X-ray Diffraction (TR-XRD): This technique captures changes in the crystal structure of the catalyst during the reaction. - Time-Resolved X-ray Absorption Spectroscopy (TR-XAS): This method provides information about the oxidation state and local environment of specific elements within the catalyst.
