Glycerol and Ethanol Oxidation in Alkaline Medium Using PtCu/C Electrocatalysts
(Esg, 2018-02-01)
The performance of platinum-copper electrocatalysts synthesized in different ratios (100:0, 90:10, 70:30, 50:50, and 0:100), using a borohydride reduction method for electrochemical oxidation of different fuels, was evaluated ...
New understandings of ethanol oxidation reaction mechanism on Pd/C and Pd2Ru/C catalysts in alkaline direct ethanol fuel cells
(2018-05-01)
Ethanol oxidation reaction (EOR) on Pd2Ru/C and Pd/C catalysts in alkaline media is studied comprehensively by cyclic voltammetry, chronoamperometry, in situ FTIR, single fuel cell test and electrochemical impedance ...
The Fabrication and Characterization of a Nickel Nanoparticle Modified Boron Doped Diamond Electrode for Electrocatalysis of Primary Alcohol Oxidation
(Wiley-v C H Verlag Gmbh, 2009-12-01)
We report the fabrication of a Ni nanoparticle modified BDD electrode and its application in the electrocatalysis of primary alcohol electrooxidation. Modification was achieved via electrodeposition from Ni(NO3)(2) dissolved ...
The benefits of ethanol use for hydrogen production in urban transportation
(Pergamon-Elsevier B.V. Ltd, 2009-12-01)
The purpose of this paper is to describe the benefits of sugar cane ethanol in Brazil, appointing the productivity of this type of fuel based on hectares of plantation, its carbon dioxide cycle and the contribution to ...
Electro-oxidation of ethanol on PtSn/CeO(2)-C electrocatalyst
(SPRINGER, 2009)
PtSn/CeO(2)-C electrocatalyst was prepared in a single step by an alcohol-reduction process using ethylene glycol as solvent and reducing agent and CeO(2) (15 wt%) and Vulcan XC72 (85 wt%) as supports. The performance for ...
The Determination of Methanol Using an Electrolytically Fabricated Nickel Microparticle Modified Boron Doped Diamond Electrode
(Wiley-v C H Verlag Gmbh, 2010-03-01)
A nickel modified boron doped diamond (Ni-BDD) electrode and nickel foil electrode were used in the determination of methanol in alkaline solutions. The Ni-BDD electrode was electrodeposited from a 1 mM Ni(NO(3))(2) solution ...
Ethanol vs. glycerol: Understanding the lack of correlation between the oxidation currents and the production of CO2 on Pt nanoparticles
(Elsevier Science Sa, 2014-03-15)
In the last decades ethanol and glycerol arose as potential fuels for fuel cells. Based on their importance to the field and molecular similarity, here we compare the electrooxidation of ethanol and glycerol on platinum ...
