On the interaction between Co- and Mo-complexes in impregnation solutions used for the preparation of Al2O3-supported HDS catalysts: A combined Raman/UV–vis–NIR spectroscopy study

Autor: Bert M. Weckhuysen, Tom Visser, Jaap A. Bergwerff

Publikováno v: Catalysis Today. 130:117-125

Research has been carried out on the formation of cobalt (Co) and molybdenum (Mo) complexes in CoMo-solutions, which are used for the preparation of Al 2 O 3 -supported hydrodesulphurization (HDS) catalysts. Aim of this study was to obtain more insig

Hydration effects on the molecular structure of silica-supported vanadium oxide catalysts: A combined IR, Raman, UV–vis and EXAFS study

Autor: Daphne E. Keller, Bert M. Weckhuysen, Fouad Soulimani, Tom Visser, DC Diek Koningsberger

Publikováno v: Vibrational Spectroscopy. 43:140-151

The effect of hydration on the molecular structure of silica-supported vanadium oxide catalysts with loadings of 1–16 wt.% V has been systematically investigated by infrared, Raman, UV–vis and EXAFS spectroscopy. IR and Raman spectra recorded dur

Influence of the preparation method on the hydrotreating activity of MoS2/Al2O3 extrudates: A Raman microspectroscopy study on the genesis of the active phase

Autor: Jaap A. Bergwerff, Krijn P. de Jong, Bert M. Weckhuysen, Bob R. G. Leliveld, Tom Visser, Marcel Jansen

Publikováno v: Journal of Catalysis. 243:292-302

Raman microspectroscopy was used to study the preparation of industrial MoS2/Al2O3 extrudates. Using this technique, the influence of the impregnation solution composition on the nature and macrodistribution of Mo complexes inside these catalyst bodi

Combining operando techniques in one spectroscopic-reaction cell: New opportunities for elucidating the active site and related reaction mechanism in catalysis

Autor: Kaisa Kervinen, T. Alexander Nijhuis, Bert M. Weckhuysen, Daphne E. Keller, Stan J. Tinnemans, J. Gerbrand Mesu, Ad M. J. van der Eerden, Andrew M. Beale, Tom Visser

Publikováno v: Catalysis Today. 113:3-15

Operando spectroscopic techniques are suitable for studying homogeneous and heterogeneous catalysts in real-time under working conditions at, e.g. elevated pressures and temperatures in the gas and liquid phase. These techniques are nowadays frequent
