Engineering of the band gap induced by Ce surface enrichment in Ce-doped SnO2 nanocrystals
(Elsevier B.V., 2020-10-15)
Surface modification of oxide semiconductors nanocrystals can promote news effects mainly in nanocrystals up to 10 nm in diameter. In these systems, the ratio surface/core is increased, and the quantum effect can not rule ...

Density functional theory study of water interactions on Mn-doped CeO2(1 1 1) surface
(Elsevier Science, 2014-06)
Spin-polarized density functional theory (DFT + U) periodic calculations have been performed to study water adsorption and dissociation on the 12.5% Mn-doped CeO2(1 1 1) surface. Our results indicated that Mn cation is the ...
DFT Study on Ce-Doped Anatase TiO2: Nature of Ce3+ and Ti3+ Centers Triggered by Oxygen Vacancy Formation
(Amer Chemical Soc, 2014-05-08)
A systematic study of TiO2 anatase, Ce-doped TiO2 anatase with 2.8 and 5.6% dopant concentration and of the systems resulting from oxygen vacancy formation has been carried out by means of periodic density functional theory ...
Effect of the CeO2 content on the surface and structural properties of CeO2-Al2O3 mixed oxides prepared by sol-gel method
(Elsevier Science BvAmsterdamHolanda, 2010)
Nanostructured Ce1-xZrxO2 Solid Solutions Produced by Mechanochemical Processing
(Elsevier Science Sa, 2013-11)
The nanostructured Ce1xZrxO2solid solutions (x0.2) have been successfully synthesized from CeCl3-ZrCl4-NaOH mixtures by mechanochemical processing as a gradual transformation, involvingin-situ CeO2and amorphous ZrO2formation ...
Potassium-promoted Ce0.65Zr0.35O2 monolithic catalysts for diesel soot combustion
(Elsevier, 2014-03)
This work presents a comparative study of Ce0.65Zr0.35O2 and CeO2 catalysts supported on cordierite for soot combustion, and the effect of potassium on the catalytic performance. The catalysts were prepared by sequential ...
Pure and Ni2O3-decorated CeO2 nanoparticles applied as CO gas sensor: Experimental and theoretical insights
(2022-01-01)
In the present work, the structural, morphological and electrical properties of CeO2 nanoparticles with spherical and rod-like morphologies and rods decorated with Ni2O3 were investigated. Morphological, structural and ...
Role of CeO2 in Rh/a-Al2O3 Catalysts for CO2 Reforming of Methane
(Springer, 2011-09-07)
The Rh/alpha-Al2O3 catalyst was modified by CeO2 in order to improve the thermal stability and the carbon deposition resistance during the CO2 reforming of methane, The carbon formation was determined by TPO, TEM and Raman ...
