AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
A synchrotron radiation photoemission study of the adsorption behaviours of ferrocene, Fe (C5H5)2, and nickelocene, Ni (CH5)2, on the Si (111) 2 X 1 surface is reported. The substrate temperature ranged between 80 and 300 K and the exposure range investiga ...
A review, with 51 refs., discusses math. models to describe the dynamics of heterogeneous catalytic reactions. To find valid kinetic models, information is needed about adsorption-desorption processes and the formation of intermediates on the catalysts sur ...
We report a synchrotron-radiation-excited photoemission study of the adsorption of W(CO)6 on Si(111)2 x 1. W(CO)6 is shown to adsorb molecularly on Si at 100 K, and to undergo dissociation at room temperature (RT). Exposure of a reacted surface at 100 K to ...
Diffuse-reflectance infrared Fourier transform (DRIFT) spectroscopy has been used to study in situ, the low-temperature (T < 200°C) methanation of CO2 over Ru on TiO2 supports and on Al2O3. For 3.8% Ru/TiO2, the reaction exhibits an activation energy (Ea) ...
In heterogeneous catalytic reactions, the rate of adsorption often falls extremely rapidly with increasing coverage. The reason can be a strong inhibition by a reactant or an increasing activation energy with coverage. Adsorption/desorption models based on ...
The methanol dehydration reaction was studied over environmentally benign, easily accessible and inexpensive K10 montmorillonite clay used as the catalyst at a temperature range between 200–700 °C. Nearly 100% selectivity towards dimethyl ether (DME) at 80 ...
