Ceria–platinum-based bilayered thin films deposited by magnetron sputtering were
developed and tested in regard to their catalytic activity for methanol oxidation by employing
a temperature-programmed reaction (TPR) technique. The composition and structure of the
samples were characterized by X-ray photoelectron spectroscopy (XPS) and scanning
electron microscopy (SEM). Both conventional (oxide-supported metal nanoparticles [NPs])
and inverse configurations (metal with oxide overlayer) were analyzed to uncover the …
