From: The dynamics of overlayer formation on catalyst nanoparticles and strong metal-support interaction

Fig. 2

EELS mapping between 455-470 eV of EELS spectra of platinum particles on TiO2 in H2 at 600 °C for 1 h (a), after a switch to O2 (b), and back to H2 (c) and the corresponding EELS spectra (d) taken from the areas indicated a, b, and c. Dynamic structural changes in the titania overlayer on platinum upon switching the gas atmosphere: from O2 to H2 (e) and from H2 to O2 (f, g). Scale bar represents 5 nm.
