Nanoscale architecture of ceria-based model catalysts: Pt–Co nanostructures on well-ordered CeO2(111) thin films

Metal–Support Interaction and Charge Distribution in Ceria-Supported Au Particles Exposed to CO

“…High-resolution SRPES measurements were performed at the Materials Science Beamline (MSB), Elettra Synchrotron Light Facility in Trieste, Italy. 52 , 53 The Ce 3d, Au 4f, O 1s, C 1s, and Cu 2p regions were recorded in UHV at room temperature using an Al Kα X-ray source and also Au 4f region using synchrotron radiation (180 eV).…”

Inorganic non-carbon supported Pt catalysts and synergetic effects for oxygen reduction reaction

“…187,188 Variable valence also provides oxygen storage and mobility, which facilitates the dynamic process of ORR. 92,189,190 Libuda et al carried out in-depth research on the system of CeO 2 supported Pt catalyst. They identified the specific process of SMSI on Pt and CeO 2 support.…”

Direct Visualization of the Formation about Inverse Catalyst CoO(x)/Pt(111)

“…Atomic layer deposition (ALD) is considered to be an ideal technique for precise construction of metal subnanocatalysts with tunable atom numbers, owing to its self-limiting and atom-by-atom growth characteristics. − A comprehensive understanding of the detailed chemical mechanism of ALD, especially during the initial few cycles, is indispensable for optimizing catalyst growth at the nanoscale. − Cobaltocene is commonly employed as the metal reaction source for depositing cobalt oxide in ALD systems. , Our objective of our work is to utilize ALD to produce CoO ( x ) islands on Pt(111), thereby creating controlled perimeter boundaries between Pt and CoO ( x ) . This is a key region for studying catalytic active sites, especially in dehydrogenation reactions.…”
