Fig. 7: The schematics of the inactive and active structure of the Pt nanocluster/CeO2.
From: Dynamic structure of active sites in ceria-supported Pt catalysts for the water gas shift reaction
At LT (low temperature (LT) < 180 °C), the catalyst is inactive while at HT (high temperature (HT): 180–300 °C), the catalyst is active. In the schematics, the red and blue spheres represent Pt atoms that are metallic (zero state) and oxidized (2+), respectively. For the active structure, the two maroon spheres represent active perimeter Pt sites.
