Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
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.
Syntheses of thermally stable chromium-incorporating hexagonal mesoporous aluminophosphate and cubic Cr-MCM-48 were reported. Characterization of the catalysts was made using low angle XRD, N2 adsorption, UV-VISDRS, thermal anal., ICP-AES and ESR. Mesoporo ...
Pure and K-doped vanadia/titania prepared by different methods have been studied in order to elucidate the role of vanadia species (monomeric, polymeric, bulk) in catalytic toluene partial oxidation. The ratio of different vanadia species was controlled by ...
New methods that allow the generation of transition metal-based catalysts and receptors are discussed. It is shown that heterobimetallic, halogeno-bridged complexes are well-suited for screening assays in combinatorial catalysis. Metal catalysts with a str ...
The prepn. of mesoporous Cr/AlPO was carried out under hydrothermal conditions. The catalyst was characterized by low angle XRD, N-adsorption, diffuse reflectance UV-visible spectroscopy, ESR and thermal anal. The catalytic activity was tested for vapor ph ...
By checking the chemistry underlying the concept of "supramolecular cluster catalysis" we identified two major errors in our publications related to this topic, which are essentially due to contamination problems. (1) The conversion of the "closed" cluster ...
The catalytic activity of Rh for the partial oxidn. of methane to syngas can be markedly affected by interfacing polycryst. Rh films with a dispersed TiO2 interlayer deposited on YSZ. High CO selectivity (near 97%) can be reached in wide range of CH4:O2 ra ...
The new water-soluble ruthenium-nitrosyl complexes [RuCl3(NO)(TPPMS)(2)] and [RuCl3(NO)(TPPTS)(2)] were synthetized and characterized by IR, H-1 and P-31 NMR spectroscopies. The NO stretching frequencies, nu(NO) = 1870 cm(-1) (TPPMS) and 1883 cm(-1) (TPPTS ...
The role was studied, of bulk V2O5 in vanadia/titania catalysts in partial oxidn. of toluene. Two catalysts with 1.8 and 11.1% of V were studied, by in situ DRIFTS and transient-response methods. Bulk V2O5 was found by FT-Raman spectroscopy only in the 11. ...
Pure and K-doped vanadia/titania catalysts have been studied by transient response method and in situ DRIFTS during toluene partial oxidn. They were characterized by FT-Raman spectroscopy, TPR, TPD of pyridine and XPS. In order to elucidate the role of dif ...
