Infrared absorption spectroscopy has proven to be one of the most powerful spectroscopic
techniques available for the characterization of catalytic systems. Although the history of IR …

Gold ([Xe] 4f 14 5d 10 6s 1) is one of the most ancient themes of investigation in science and
arts, and its renaissance now leads to an exponentially increasing number of publications …

Acetoxylation of ethylene to vinyl acetate (VA) was used to investigate the mechanism of the
promotional effect of gold (Au) in a palladium (Pd)-Au alloy catalyst. The enhanced rates of …

Vinyl acetate monomer (VAM), an important chemical intermediate in industry, is produced
by the well-established commercial process of acetoxylation of ethylene with Pd–Au/SiO2 …

The surface composition of a Pd–Au alloy was determined using low energy ion scattering
spectroscopy (LEISS). A stable surface composition was found between 700 and 1000K with …

First-principles screening approaches exploiting energy trends in surface adsorption
represent an unparalleled success story in recent computational catalysis research. Here we …

This study reports evidence for catalytic deoxygenation of alkanols, alkanals, and
alkanediols on dispersed Cu clusters with minimal use of external H2 and with the …

The high adsorbate coverages that form on the surfaces of many heterogeneous catalysts
under steady-state conditions can significantly lower the activation energies for reactions …

PdAu catalysts supported on both pure silica and aluminosilicates and promoted with KOAc
are the most active and selective compositions for the industrial-scale acetoxylation of …

On Pd (111), thermal activation of ethylene has been reported to yield ethylidyne. Using
more approximate models, a plausible three-step mechanism, ethylene→ vinyl→ …
