(Universidade Estadual Paulista (UNESP), 2014)
Catalisadores 'PT' e 'PTSN' modificados com 'SN''O IND.2' para a oxidação eletroquímica de etanol
(Universidade Estadual Paulista (Unesp), 2011-02-25)
Com o intuito de avaliar a influência da presença de óxido na resposta eletrocatalítica para a oxidação de etanol, foram preparados quatro materiais constituídos de partículas metálicas de Pt ou liga PtSn, suportados sobre ...

Effect of Ni on Pt/C and PtSn/C prepared by the Pechini method
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
Different compositions of Pt, PtNi, PtSn, and PtSnNi electrocatalysts supported on carbon Vulcan XC-72 were prepared through thermal decomposition of polymeric precursors. The nanoparticles were characterized by morphological ...
Anodic oxidation of formaldehyde on Pt-modified SnO2 thin film electrodes prepared by a sol-gel method
(Elsevier B.V., 2004-09-15)
Pt-modified SnO2 electrodes were prepared onto titanium substrates in the form of thin films of similar to2 mum at different temperatures in the range from 200 to 400degreesC. Surface morphology was examined by scanning ...

The electro-oxidation of carbon monoxide and ethanol on supported Pt nanoparticles: The influence of the support and catalyst microstructure
(2013-07-01)
The sluggish kinetics of ethanol oxidation on Pt-based electrodes is one of the major drawbacks to its use as a liquid fuel in direct ethanol fuel cells, and considerable efforts have been made to improve the reaction ...
