Enhanced oxidation activity from modified ceria: MnOx–ceria, CrOx–ceria and Mg doped VOx–ceria
Applied Catalysis B: Environmental, 2016 Abstract Ceria is an important component of catalysts for oxidation reactions that proceed through the Mars-van Krevelen mechanism, promoting activity. A paradigm example of this is the VOx–CeO2 system for oxidative dehydrogenation reactions, where vanadium oxide species are supported on ceria and a special synergy between them is behind the enhanced

Electrochemical deposition of ceria and doped ceria films
Ceramics International, 2001Abstract Cathodic electrodeposition of CeO 2 and Ce 1− x Gd x O 2− y was performed from aqueous and mixed ethyl alcohol-water solutions of CeCl 3 and GdCl 3 on Ni foil and Ni–yttria stabilized zirconia substrates. The influence of hydrogen peroxide on the electrodeposition process was studied.

Ceria-hafnia, ceria-terbia, and ceria-praseodymia solid solutions were prepared by the citric-acid (Pechini) method and characterized using X-ray diffraction (XRD) for structure and coulometric titration for redox thermodynamics. Following calcination at 973 K, XRD showed that both Ce(0.5)Hf(0.5)O2 and Ce(0.8)Hf(0.2)O2 exist as single-phase solid ...

Ozonation of bezafibrate over ceria and ceria supported on carbon materials
Environmental Technology, 2014Two catalysts containing ceria dispersed on the surface of multi-walled carbon nanotubes and activated carbon were investigated as ozonation catalysts for the mineralization of bezafibrate (BZF). The results were compared with those obtained in the absence of the catalyst and in the presence of the parent carbon materials, as well as in the presence of

Water Chemistry on Model Ceria and Pt/Ceria Catalysts
The Journal of Physical Chemistry C, 2012We have studied the interaction of water with stoichiometric CeO2(111)/Cu(111), partially reduced CeO2–x/Cu(111), and Pt/CeO2/Cu(111) model catalysts by means of synchrotron–radiation photoelectron spectroscopy (SRPES), resonant photoemission spectroscopy (RPES) at the Ce 4d edge, infrared reflection absorption spectroscopy (IRAS), and density ...
