Ethanol electro-oxidation on carbon-supported Pt-Ru, Pt-Rh and Pt-Ru-Rh nanoparticles
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
This work investigates the effects of carbon-supported Pt, Pt-Ru, Pt-Rh and Pt-Ru-Rh alloy electrocatalysts oil the yields of CO2 and acetic acid as electro-oxidation products of ethanol. Electronic and structural features ...
Electrocatalysis of ethanol oxidation on Pt monolayers deposited on carbon-supported Ru and Rh nanoparticles
(ELSEVIER SCIENCE BV, 2008)
Pt monolayers deposited on carbon- supported Ru and Rh nanoparticles were investigated as electrocatalysts for ethanol oxidation. Electronic features of the Pt monolayers were studied by in situ XANES (X-ray absorption ...
Influence of alcohol additives in the preparation of electrodeposited Pt-Ru catalysts on oxidized graphite cloths
(Elsevier Science Sa, 2011-03)
Carbon supported Pt-Ru catalysts were prepared by multiple cycles of potentiostatic pulses from aqueous diluted chloroplatinic acid and ruthenium chloride solutions in the presence of ethanol or ethylene glycol at pH 2 and ...
A DFT study of H adsorption on Pt(111) and Pt-Ru(111) surfaces
(Elsevier Science, 2008-07)
In this work a comparative analysis between different Pt-Ru(111) surface models and pure Pt(111) surface is presented. Some aspects of the electronic structure of the surfaces and hydrogen adsorption are analysed based on ...
PtRu/C electrocatalysts prepared using electron beam irradiation
(Sao Paulo: ABEN, 2007, 2014)
Electrocatalysis on noble metal and noble metal alloys dispersed on high surface area carbon
(Ecole Polytechnique Montreal, 2003-01-01)
In this work, a simple route to prepare carbon supported Pt/C, Pt:Ru/C, Pt:Mo/C and Pt:Ru:Mo/C catalysts is reported. The electrochemical properties of the several carbon materials used as substrates in the absence and in ...
