Methanol decomposition on a clean polycrystalline copper oxide surface was studied by x-ray photoelectron spectroscopy (XPS). Methanol was adsorbed at 133 K and desorbed over a broad temperature range. When CuO was exposed to a very low dose of methanol vapor, dissociative adsorption takes place, leading to the formation of CH3O and H2O. This is attributed to the presence of preadsorbed oxygen on the CuO surface.

Layer Method

The use of an intermediate barrier layer to vary the penetration depth in an ATR experiment is investigated. Both theoretical and experimental results suggest that this method may be useful in probing concentration profiles away from the interface, particularly in the case of thin films, where variable-angle methods have limitations. Application of this technique in the study of poly(methylmethacrylate)/poly(dimethylsiloxane) (PMMA/PDMS) graft copolymers deposited onto a copper oxide surface indicates a preferential presence of the siloxane component at the oxide interface, a concentration which tends to decrease with increasing distance into the bulk of the sample film.

Ceria-coated copper oxide powders were prepared by the precipitation method using cerium nitrate hexahydrate and ammonia as a precipitant. Heterogeneous nucleation and growth of ceria took place on the copper oxide surface by dispersing the copper oxide particles in cerium nitrate aqueous solution and subsequently adding ammonia into it. Process conditions such as the pH of the precursor solution and precipitation temperatures were carefully controlled for the homogeneous precipitation of ceria particles. It was found that copper oxide was homogeneously coated with nano-sized (~20 nm) ceria particles at room temperature. The morphology of ceria and ceria-coated copper oxide powder were examined by field-emission scanning electron microscopy (FE-SEM) as a function of precipitation temperature.
