Low-loading Pt/β-MoC catalyst for ethanol dissociation. Experimental and theoretical characterization.

The adsorption and dissociation of ethanol on Pt/β-MoC with a low noble metal loading (0.1 wt%) is studied in the context of catalytic H production from alcohols. X-ray diffraction and experimental results indicate that Pt modifies the lattice parameters of β-MoC.

1D tungsten oxide nanostructures on a Cu(1 1 0) surface.

Thin epitaxial layers of tungsten oxide on metal substrates are suitable as model systems for investigation of chemical reactivity and catalytic properties. However, the ability to prepare epitaxial tungsten oxide model system in situ is quite rare. Here we present a method to prepare highly ordered tungsten oxide thin film on a Cu(1 1 0) single crystal substrate using physical vapor deposition in a reactive atmosphere of atomic oxygen.
