Like an 'eye on the inside' … … tomographic energy dispersive diffraction imaging is used to obtain 3D information on the phase and element distribution of metal oxides in catalyst extrudate bodies (the pellets in the cover picture). In the Communication on page 8832 ff., B. M. Weckhuysen and co‐workers use Co–Mo/Al 2 O 3 hydrodesulfurization catalysts to showcase the technique and its capacity to discriminate between crystalline and noncrystalline phases. They show that 1D and 2D studies oversimplify the challenge of relating catalyst performance to a preparation method.
