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 - PPGEQ, 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 - PPGEQ, 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 ...
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 ...
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 ...

Time-resolved spectroscopy studies of Gd2SiO5 : Ce3+ from spherical particles
(Elsevier B.V., 2002-10-07)
This paper reports on time-resolved emission and excitation spectra measurement studies of Gd2SiO5:Ce3+ in powder or pellet samples, from spherical particles, in order to assign the Ce3+ ion transitions into two different ...
