Abstract

The chemical properties of catalysts often depend on the size, shape and structure of the supported metal particles. One of the main objectives for HREM study of catalysts is to characterize these morphological features and relate them to catalysis. Image simulations may help in the interpretation at HREM images of supported particles in particular to extract useful information about the size, shape and structure of the particles and it should also be a useful tool for evaluating the imaging conditions in terms of visibility of supported particles. In this study, images of Pt and Re particles supported on TiO 2 (rutile) were calculated in both plan view and profile view in order to better understand the influence of a crystalline support on the visibility and apparent morphological features of supported fine particles.
