Estudo da decomposição térmica de oxalato de estrôncio dopado com cério(III) como precursor de materiais luminescentes
(Editora Unesp, 2002-01-01)
Este trabalho trata da obtenção de SrC2O4, Ce2(C2O4)3, e SrC2O4 dopado com diferentes porcentagens de Ce3+ como precursores do luminóforo azul Sr2CeO4. Os precursores preparados foram estudados por TG e DTA. Uma mistura ...
Efeito do teor de CeO2 em catalisadores de Pt/CeO2-Al2O3 para as reações de oxidação parcial e reforma do metano.
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-graduação em Engenharia Química, 2005-03-10)
The effect of CeO2 loading in Pt/CeO2-Al2O3 catalysts was investigated. Pt
catalysts supported on mixed CeO2-Al2O3 carriers with different CeO2 loading 1,
3, 6, 12, 20 wt.% were prepared by incipient wetness impregnation ...
Catalisadores de Cu/CeO2 modificados com La aplicados à reação de deslocamento gás-água
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-graduação em Engenharia Química, 2013-03-14)
The water gas shift reaction (WGSR) is often used in industrial processes in order to increase hydrogen production, as well as to remove quantities of CO in the chains produced by steam reforming of hydrocarbons. In this ...
Highly active Rb/Cu/YCeO2 catalyst for the storage of nitric oxide under lean conditions
(ELSEVIER SCIENCE BV, 2016)
A novel Pt-free Rb/Cu/YCeO2 catalyst was applied to the adsorption of NO under oxidizing conditions. The results show a much greater performance of this catalyst relative to a Pt/Ba/Al2O3 catalyst. The results suggest that ...

CuO and CeO2 catalysts supported on Al2O3, ZrO2, and SiO2 in the oxidation of CO at low temperature
(ELSEVIER, 2008-07-01)
The effect of the support, Al2O3, ZrO2, and SiO2, on the activity for CO oxidation of a series of CuO and CeO2 monometallic and bimetallic catalysts was studied. The catalysts were prepared by coimpregnation of the support ...
Co/ZrO2, Co/CeO2 and MnCoCe structured catalysts for COPrOx
(Elsevier, 2013-11)
Cordierite monoliths washcoated with MnCoCe(CP), Co(I)/ZrO2 and Co(I)/CeO2 catalysts were prepared and studied for the CO preferential oxidation (COPrOx) reaction. Among them, the MnCoCe/M system presented the best CO ...
Line defect Ce3+ induced Ag/CeO2/ZnO nanostructure for visible-light photocatalytic activity
(Elsevier Science SA, 2018)
This article reports, synthesis and characterization of the ternary Ag/CeO2/ZnO nanostructure which was tested for visible light photocatalytic degradation of industrial textile effluent. The HR-TEM and XPS results confirms ...
