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.
V substituted phosphomolybdic acids could hydroxylate benzene with nearly 100% selectivity at appreciable conversion levels in the presence of oxidizing agents like H2O2 and AcOOH. There appears to be a correlation, for the liq. phase, between phenol yield ...
The work presents the effect of K-doping on V/Ti-oxides taking into account: the surface acid–base properties and the structure of surface vanadia species in respect to the catalyst performance and deactivation. The structure of active surface species dete ...
The deprotonation energies of benzene, chlorobenzene, all di-, tri-, tetrachlorobenzenes, and pentachlorobenzene have been detd. in the gas phase using a Fourier transform ion cyclotron resonance mass spectrometer. The values measured differ only slightly, ...
Fiber catalysts are easy to handle and free of mass-transfer resistance. This report is the first application of cloth catalysts to water denitrification. In this work, cloths woven from glass fibers (GF) of 7–10 mm in diameter, impregnated with Pd, were t ...
We report a simple way to synthesize carbon nanotubes and nanostructures from the solid phase. Vacuum annealing of diamond-like carbon (DLC) films or polyethylene mixed with catalyst in argon atmosphere leads to the formation of nanotubes and nanostructure ...
The present work deals with two subjects. The interaction of NO2 and HONO with different types of soot are examined in the first part whereas in the second part an experimental set-up is presented which has been built in order to measure the kinetics of th ...
The electrochem. promotion of RuO2 catalysts interfaced with yttria stabilized zirconia was studied for the combustion of ethylene. The complete oxidn. of ethylene can be described by an Eley-Rideal type mechanism. In situ work function measurements were u ...
A model for the electrochem. promotion induced by electrochem. generated promoting species is proposed. The formation rate of promoters is assumed to be proportional to the availability of free surface sites at the solid electrolyte/catalyst/gas three-phas ...
An aq. soln. of peroxynitrous acid has been studied using first-principles mol. dynamics simulations based on d. functional theory. The relative Helmholtz energies of different conformers have been detd. via thermodn. integration with constraints. At contr ...
Thick GaN layers grown by HVPE on different starting layers were examined. The resulting layers were found to be homogeneous with good crystalline and surface quality over the whole 2-inch wafer, strongly depending on the starting layers and gas phase comp ...
