Fig. 1: Evolution and dynamic structural changes of the overlayer in SMSI.
From: The dynamics of overlayer formation on catalyst nanoparticles and strong metal-support interaction
A platinum particle on a titania support in the first exposure to H2 at 600 °C (a, b) and the subsequent atmosphere change to O2 at 600 °C (c), a switch to H2 (d) and then a switch to O2 again (e), and interpretation of the phenomena based on the combined results of in situ transmission electron microscopy, in situ X-ray photoemission spectroscopy, and in situ powder X-ray diffraction (f–j). Insets for c–e show a magnified image of the overlayer structure observed. Scale bar is 5 nm.
