Catalytic Combustion of n-Hexane Over Alumina Supported Mn–Cu–Ce Catalysts
(Springer, 2013-08-15)
Supported MnCuCe and MnCe mixed oxides catalysts were prepared and evaluated in n-hexane combustion reaction. They presented an excellent catalytic activity in total combustion of n-hexane. Catalysts were characterized by ...
CeO2 nanoparticle morphologies and their corresponding crystalline planes for the photocatalytic degradation of organic pollutants
(ACS Publications, 2019-09-17)
Currently, numerous properties of semiconducting oxides are correlated to their morphological characteristics resulting from their exposed surfaces. In the present work, the relationship between the following morphologies ...
Toward an Understanding of Selective Alkyne Hydrogenation on Ceria: On the Impact of O Vacancies on H 2 Interaction with CeO 2 (111)
(American Chemical Society, 2017-11)
Ceria (CeO2) has recently been found to be a promising catalyst in the selective hydrogenation of alkynes to alkenes. This reaction occurs primarily on highly dispersed metal catalysts, but rarely on oxide surfaces. The ...
Color tunability in green, red and infra-red upconversion emission in Tm3+/Yb3+/Ho3+ co-doped CeO2 with potential application for improvement of efficiency in solar cells
(Elsevier B.V., 2015-03-01)
The preparation of Tm3+/Yb3+/Ho3+ co-doped CeO2 prepared by the precipitation method using ammonium hydroxide as a precursor is presented. By X-ray diffraction the materials show the phase-type of fluorite structure and ...
XPS and DRIFTS study of cerium in Ce-Si-Al-O-N glasses
(Trans Tech Publications, 2000-12)
Glasses belonging to the Ce-Si-Al-O-N system have been prepared by heating physical mixture of CeO2, AlN and SiO2 under N2.
Thermodynamics and Lithium Intercalation in CeO(2)-TiO(2) Thin Film
(TAYLOR & FRANCIS LTD, 2010)
The kinetics and the thermodynamics of electrochemical intercalation of lithium into CeO(2)-TiO(2) films prepared by the sol-gel process were studied by galvanostatic intermittent titration technique (GITT) as function of ...
CO preferential oxidation on cordierite monoliths coated with Co/CeO2 catalysts
(Pergamon-Elsevier Science Ltd, 2012-03)
Cordierite monoliths washcoated with Co/CeO2 catalysts prepared from different methods were studied for the CO preferential oxidation reaction. Powder catalysts were also studied for the sake of comparison and in order to ...
Influence of synthesis time on the morphology and properties of CeO2 nanoparticles: an experimental-theoretical study
(ACS Publications, 2020-07-06)
Here we combined experimental and theoretical results to correlate the morphological, optical, and electronic properties of cerium oxide (CeO2) prepared by a microwave-assisted hydrothermal method with varying synthesis ...
Density functional theory (DFT) study of H2S interactions on the pr-doped CeO2(111) surface
(Asociación Química Argentina, 2017-04)
En este trabajo presentamos un estudio basado en la teoría del funcional de la densidad (density functional theory, DFT) de las interacciones del H2S sobre la superficie CeO2(111) dopada con un bajo contenido de praseodimio ...
