We show that image simulation is invaluable for the interpretation of time-dependent environmental transmission electron microscopy (ETEM) images. Experimental ETEM images of a crystalline nanoparticle catalyst (NPC) during the growth of carbon nanotubes were compared with simulated images of the Fe21Mo2C6 structure that was observed along various directions. Lattice images that appear in the NPC at different times can be accounted for by considering only the Fe21Mo2C6 structure. (C) 2012 Elsevier Ltd. All rights reserved.
