A New Type of Strong Metal–Support Interaction and the Production of H 2 through the Transformation of Water on Pt/CeO 2(111) and Pt/CeOx/TiO 2(110) Catalysts

The electronic properties of Pt nanoparticles deposited on CeO(2)(111) and CeO(x)/TiO(2)(110) model catalysts have been examined using valence photoemission experiments and density functional theory (DFT) calculations. The valence photoemission and DFT results point to a new type of "strong metal…
