Electron holography is an emerging technique for catalyst characterization. In conventional high resolution transmission electron microscopy (HRTEM) image intensities are recorded, but the phase information in the complex image wave is lost. However, it is the phase information which is sensitive at the atomic scale to changes in sample thickness and composition. Electron holography allows us to obtain the amplitude and phase of the electron wave independently from the hologram. This technique is therefore of great interest to map out the structure and morphology of catalytic materials. We will describe applications of this technique to supported metals, oxides and sulfide catalysts.
