Surface Chemistry of Ruthenium Dioxide in Heterogeneous Catalysis and Electrocatalysis: From Fundamental to Applied Research

Asymmetric catalysis at chiral metal surfaces.

Promoters of metal catalysts play an essential role in the hydrogenation of unsaturated bonds, such as in carbonylic compounds. This promotion is a key to a high selectivity to unsaturated alcohols in hydrogenation of α,β-unsaturated aldehydes. Analysis of the information available in the literature on the adsorptions through the C—C and C—O groups, respectively, together with the information on the catalytic behaviour of the promoter-free and promoted catalysts, allows us to suggest a model of surfaces active in selective hydrogenation of unsaturated aldehydes.

Adsorption of acetone both on the clean ruthenium(001) surface and on the ruthenium(001) surface modified chemically by the presence of an ordered oxygen adatom overlayer

High-resolution electron-energy-loss measurements and relevant theoretical calculations for the vibrational structure of ordered oxygen overlayers on the Ru(001) surface are presented. The vibrational spectrum of the $p(2\ifmmode\times\else\texttimes\fi{}2)$ overlayer shows a single dipolaractive mode above the substrate phonon band. Because of a reduction in symmetry of the threefold adsorption site, however, the vibrational spectrum of the $p(1\ifmmode\times\else\texttimes\fi{}2)$ overlayer is fundamentally different, showing two dipolar-active modes above the substrate phonon band.
