The oxidation of benzaldehyde to benzoic acid with V2O5, SnO2-promoted V2O5 and MnO2 as catalysts has been investigated. The reaction mechanism includes the following steps: dissociative chemisorption of benzaldehyde, yielding an asymmetric covalent

Ce-promoted and unpromoted Pd/ZSM5 catalysts were prepared, characterized by TPR, XPS and TEM, and tested for the dehydroisomerization of α-limonene to p-cymene. At 300°C the conversion is near 100% over all samples, but the selectivity to p-cymene

The discussion is devoted to some controversial points related to the aromatization of paraffins at high temperature (around 500°C), and low hydrogen pressure (1–8 bar) over non-acidic catalysts, in particular platinum plus a second component on a

The heat of adsorption of Xe and the change in work function by Xe adsorption have been investigated on Cu, Au, Ni, Pt and Rh films using the photoelectron emission technique. The surface potential of Xe appears to be directly related to the heat of
