Desempenho de filtros fibrosos operando na remoção de partículas nanométricas de aerossóis
(Universidade Federal de São Carlos, 2007-02-28)
The increase in the air pollution in the last decades is causing a strong increase in the
monitoring and control of emissions of particulate matter in the atmosphere, in order to
minimize the problems caused to the ...
Nanopartículas de Co suportadas em SiO2: síntese, caracterização e propriedades catalíticas para a reforma a vapor do etanol
(Universidade Federal de São Carlos, 2007-03-16)
Colloidal Co Nanoparticles (Co-NPs) were used to prepare supported Co catalysts. The Co-
NPs were obtained by thermal decomposition of the precursor Co2(CO)8 in the presence of
oleic acid and trioctylphosphine oxide ...
Nanopartículas de Pt suportadas em Al2O3 e CeO2-Al2O3: síntese, caracterização e propriedades catalíticas para reforma do metano.
(Universidade Federal de São Carlos, 2007-03-16)
A new method to prepare Pt nanoparticles (NPs) dispersed on Al2O3 and CeO2-Al2O3
is described in this work. The Pt-NPs were used to prepare CeO2-Al2O3-supported Pt
nanocatalysts (Pt-NPs/Al2O3 and Pt-NPs/CeO2-Al2O3). The ...
