Borohydride electrooxidation on Au and Pt electrodes
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
Direct borohydride fuel cells (DBFCs) are attractive energy generators for powering portable electronic devices, mainly due to their high energy density and number of electrons per borohydride ion. However, the lack of a ...
Electrooxidation of ethanol on Pt and PtRu surfaces investigated by ATR surface-enhanced infrared absorption spectroscopy
(Sociedade Brasileira de Química, 2012)
Herein, it was investigated for the first time the electro-oxidation of ethanol on Pt and PtRu electrodeposits in acidic media by using in situ surface enhanced infrared absorption spectroscopy with attenuated total ...
Dissociation and electrooxidation of primaquine diphosphate as an approach to the study of anti-chagas prodrugs mechanism of action
(Elsevier B.V., 2001-01-01)
This paper describes the voltammetric behavior of primaquine as a previous support to the further understanding of the delivery and action mechanisms of its respective synthesized prodrugs. There are few papers describing ...
Rh-decorated Ptirox Nanoparticles For Glycerol Electrooxidation: Searching For A Stable And Active Catalyst
(ELSEVIER SCIENCE BVAMSTERDAM, 2016)
Effect of amine ligands on stabilization of pt nanoparticles as electrode materials for electro-oxidation of methanol
(Journal of New Materials for Electrochemical Systems Volume 14, Issue 1, 2011, Pages 1-10, 2011)
Pt-stabilized catalysts with platinum crystallites sizes between 1-20 nm were prepared using an organometallic approach and three different amino ligands; tert-butylamine, 1,3-diaminopropane and anthranilic acid. The ...
Ethanol electro-oxidation in an alkaline medium using Pd/C, Au/C and PdAu/C electrocatalysts prepared by electron beam irradiation
Carbon-supported Pd, Au and bimetallic PdAu (Pd:Au 90:10, 50:50 and 30:70 atomic ratios) electrocatalysts were prepared using electron beam irradiation. The obtained materials were characterized by energy dispersive X-ray ...
Effect of temperature on the electro-oxidation of ethanol on platinum
(Sociedade Brasileira de Química, 2010)
We present in this work an experimental investigation of the effect of temperature (from 25 to 180 ºC) in the electro-oxidation of ethanol on platinum in two different phosphoric acid concentrations. We observed that the ...
