Wet air oxidation of acetic acid over platinum catalysts supported on cerium-based materials: Influence of metal and oxide crystallite size

Autor: J. Mikulova, D. Mesnard, Daniel Duprez, Sylvie Rossignol, Jacques Barbier, Charles Kappenstein

Publikováno v: Journal of Catalysis. 251:172-181

Platinum catalysts (2.5 wt%) prepared by impregnation on pure commercial ceria and on Zr 0.1 (Ce 0.75 Pr 0.25 ) 0.9 O 2 sol–gel mixed oxide were synthesized and used for catalytic wet air oxidation (CWAO) of acetic acid. The influence of the platin

Properties of cerium–zirconium mixed oxides partially substituted by neodymium: Comparison with Zr–Ce–Pr–O ternary oxides

Autor: François Gérard, J. Mikulova, Sylvie Rossignol, Daniel Duprez, D. Mesnard, Charles Kappenstein

Publikováno v: Journal of Solid State Chemistry. 179:2511-2520

CeO{sub 2} doped with praseodymium, neodymium and/or zirconium atoms were prepared by coprecipitation and by the sol-gel method. Structural properties were investigated by in situ XRD and Raman spectroscopy while oxygen storage capacity (OSC) was mea

Structural changes of Ce–Pr–O oxides in hydrogen: a study by in situ X-ray diffraction and Raman spectroscopy

Autor: D. Mesnard, Daniel Duprez, Charles Kappenstein, Sylvie Rossignol, François Gérard

Publikováno v: J. Mater. Chem.. 13:3017-3020

Ce–Pr–O mixed oxides prepared by coprecipitation and calcined at 1173 K reveal a non stoichiometric structure with oxygen vacancies in the bulk. In situ XRD and Raman spectroscopy were used to investigate these properties simultaneously and ident
