NMR studies of acetylene absorbed on supported platinum catalysts
… acetylene (C2H2) adsorbed at room temperature on supported platinum catalysts. Measurements from 77""K to 158°K of the spin-lattice relaxation behavior of carbon-13 reveal multiple-exponential behavior. Calculations rule out an anisotropic T 1 as an explanation for the multiple-exponential …

A new approach to the study of surface phenomena, measurements of diffusion rates, intermolecular distances and electronic properties of CO chemisorbed on supported platinum catalysts by nuclear magnetic resonance
… resonance to study the chemisorption of CO on supported platinum particles. The particles are 10 to 50 Ansgtrom in diameter, supported on alumina. CO is 90% enriched with 13CO. NMR data were taken from 4 K to 600 K. He shows that a measurement of transverse relaxation at 77 K can be used to …

Stepped single crystals as improved model for supported catalysts: Ethylene, methanol and assorted molecules on platinum(511) and platinum(331)
… from ethylene or ethane has been reported for supported platinum catalysts. A model for the methane formation on (1 x 1)Pt(110), was proposed by Yagasaki. In this study, the mechanism of methane formation has been further investigated, and Yagasaki's model tested, by studying the decomposition …

Trapping Platinum on Ceria: Role of Surface Facets
Supported platinum catalysts are used in the automotive industry for the oxidation of CO, hydrocarbons, and NOx. Dispersed Pt provides active sites for these reactions to occur. During the use of these catalyst, high temperatures will cause Pt to become volatile and sinter, forming large particles …
