WebAug 10, 2024 · Abstract. Water, even at trace concentrations, strongly increases the CO oxidation activities of the reducible metal oxide supported noble-metal catalysts, where the transfer of proton plays a key role. In this paper, we performed a thorough investigation of the interplay between water molecules and the reduced CeO 2 (111) surface. Webmetals emerge when dispersed as nanometer-sized particles on high–surface area oxide supports. Although simple models attribute catalytic properties mainly to size effects, with …
