Sentence examples for model catalysts in from inspiring English sources

We experimental demonstrated that model catalysts in the form of ideal Pd surfaces, either single (1 0 0) and poly crystalline, are active for H2O2 direct synthesis at 15 °C and pressure in excess of 20 bars, in methanol.

This paper reports on an experimental setup wich enables us to investigate planar model catalysts in an environment closely resembling the environment found in an actual direct methanol fuel cell.

CO2 reforming of methane has been studied over Pt/Al2O3 model catalysts in a temperature range of 600 800 °C using steady-state and transient methods (Transient Response Method (TRM) and DRIFT-MS).

In the present study, this promotion was investigated using model catalysts in which ceria films were vapor deposited onto α-Al2O3, polycrystalline ZrO2, polycrystalline Y2O3-stabilized ZrO2 (YSZ), and YSZ(1 0 0), (1 1 1), and (1 1 0) single crystals.

V2O5/TiO2 catalysts with V2O5 loadings of 1 wt.% (Eurocat EL10V1) and 8 wt.% (Eurocat EL10V8) as well as the corresponding NH3-washed samples (EL10V1w, EL10V8w) exhibiting exclusively monomeric vanadyl species were used as model catalysts in order to elucidate the role of different vanadia species in toluene oxidation.

A polycrystalline Pt foil has been investigated as model catalyst in methane catalytic partial oxidation to synthesis gas.

Besides Pd/C catalyst, Pd black was used as a model catalyst in order to exclude the effects of carbon support.

Therefore, we developed a new type of model catalyst in the form of nanofibers for assessing structural changes of CeO2-based catalysts under highly corrosive Deacon reaction conditions.

The study is based on periodic density functional theory calculations carried out for the reaction between ethene and atomic oxygen on the Ag(111) surface, taken as a model catalyst, in the presence of coadsorbed halogens.

Recent advances in the preparation and characterization of planar model catalysts and in ambient pressure surface spectroscopy enable us to investigate well-defined supported metal nanoparticles under working conditions, approaching the conditions of applied catalysis.

This is a common issue for reactors where experiments on single-crystal model catalysts are performed, in contrast to experiments carried out in flow-through reactors where it is possible to observe a 100% conversion.
