Characterization and catalytic performance of PtSn catalysts supported on Al2O3 and Na-doped Al2O3 in n-butane dehydrogenation
(Springer, 2007-11)
PtSn/Al2O3 and PtSn/Al2O3-Na catalysts display important modifications of the metallic phase with respect to Pt/Al2O3 one. In this sense, TPR and XPS results show the presence of strong interactions between Pt and Sn, with ...
Influence of Na content on the catalytic properties of Pt-Ir/Al2O3 catalysts for selective ring opening of decalin
(Elsevier, 2014-04)
The influence of the Na addition on Pt-Ir/Al2O3 on the reaction of selective ring opening of decalin and methyl cyclopentane was studied. The catalysts were evaluated by means of TPR, pyridine TPD, TEM, FTIR-CO and by the ...
Influência do teor metálico na isomerização do n-hexano sobre Ni-Pt/HUSY.
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2003-08-06)
The isomerization of linear alcanes has arised great interest in the industry of refining of oil with the intention to transform n-paraffins (particularly with 6 and 7 carbon atoms), in iso-paraffins, since these last ones ...
Reforming of CH4 with CO2 on Pt-supported catalysts: Effect of the support on the catalytic behaviour
(Elsevier Science, 2005-10)
This paper reports a study about the behaviour of different Pt-based catalysts supported on Al2O3, Na-Al2O 3, K-Al2O3 and ZrO2 in methane reforming with CO2. Results indicate that Pt/Na (0.3 wt%)-Al 2O3 and Pt/ZrO2 catalysts ...

Platinum supported on mesoporous carbon as cathode catalyst for direct methanol fuel cells
(Elsevier Science, 2015-03)
Platinum nanoparticles supported on mesoporous carbon were obtained by an impregnation and reduction method with NaBH4 as the reducing agent. The high specific surface area mesoporous carbon was obtained by carbonization ...
Searching for suitable catalysts for a passive direct methanol fuel cell cathode
(Pergamon-Elsevier Science Ltd, 2015-12)
Trimetallic PtMRu/C cathode catalysts with M = Co or Fe obtained by an impregnation procedure using ethylene glycol and NaBH4 as reducing agent, with suitable activity for the oxygen reduction reaction (ORR) and improved ...
A kinetic modeling of the liquid-phase oxidation of lactose over Pt- and Au-supported catalysts
(Springer, 2015-04)
Pt and Au catalysts, 2 wt% metal loading, supported on SiO2 and Al2O3 were used to study the effect of metal and support on the liquid-phase oxidation of lactose. Pt-based catalysts were prepared by incipient wetness ...
Catalisadores de Co e Pt suportados em La2O3 e SiO2 aplicados na reforma a vapor do etanol
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2015-03-24)
In intense search best environmental conditions, it is necessary to invest in renewable fuels, affordable and low polluting. With the aim to participate in this effort, this work was undertaken to study the steam reforming ...
