Jacques, S.D.M. and di Michiel, M. and Beale, A.M. and Sochi, Taha and O’Brien, M.G. and Espinosa Alonso, L. and Weckhuysen, B.M. and Barnes, Paul (2011) Dynamic x-ray diffraction computed tomography reveals real-time insight into catalyst active phase evolution. Angewandte Chemie - International Edition 50 (43), pp. 10148-10152. ISSN 1433-7851.
Color X-ray images can be obtained by X-ray diffraction computed tomography (XRD-CT) where the mapping of the diffraction signal from the interiors of solid objects enables material-specific imaging. In their Communication on page 10 148 ff., S. D. M. Jacques et al. describe the first time-resolved XRD-CT experiment, which reveals the mechanism by which a catalyst evolves from its precursor during the preparation of millimeter-sized industrial hydrogenation catalyst body.
