Reactivity of bimetallic nanostructured electrocatalysts for the hydrogen adsorption. An atomistic view
(Elsevier Science, 2020-07)
The reactivity and structure of bimetallic nano-arrangements deposited on Au(111) surfaces have been investigated on the basis of DFT. Several bimetallic nanostructures have been investigated: wires and clusters with ...
Oxygen reduction reaction (orr) on bimetallic AuPt and AuPd(1 0 0)–electrodes: Effects of the heteroatomic junction on the reaction paths
(Elsevier Science, 2018-05)
The seek for materials to enhance the oxygen reduction reaction (orr) rate is a highly relevant topic due to its implication in fuel cell devices. Herein, the orr on bimetallic electrocatalysts based on Au-M (M = Pt, Pd) ...
Dependence on composition of electronic properties and stability of Pt-Fe/C catalysts for oxygen reduction
(Elsevier B.V., 2010-11-01)
This work presents studies of electronic characteristics and alloy stability carried out for Pt-Fe/C catalysts of different compositions (10-50% Fe, in atoms) and same particle size. The electronic properties are characterized ...
Bimetallic nanowires as electrocatalysts for nonenzymatic real-time impedancimetric detection of glucose
(Royal Society of Chemistry, 2012-02)
Gold-platinum nanowires are proposed as electrocatalysts for a real-time nonenzymatic impedancimetric detection of glucose. The electrochemical behavior of the obtained platform toward electrocatalytic oxidation of glucose, ...
Investigation of the CO tolerance mechanism at several Pt-based bimetallic anode electrocatalysts in a PEM fuel cell
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
The electrocatalysis of CO tolerance of Pt/C, PtRu/C, PtFe/C, PtMo/C, and PtW/C at a PEM fuel cell anode has been investigated using single cell polarization and online electrochemical mass spectrometry (EMS) measurements, ...

Electrocatalytic oxidation of ethylene glycol in 0.5 M H2SO4 and 0.5 M NaOH solutions at a bimetallic deposited electrode
(ELSEVIER SCIENCE SA LAUSANNE, 1996-04-12)
The activity of Pt, Pt + Pb and Pt + Ir deposits on Ti, for ethylene glycol (EG) oxidation, was studied in both 0.5 M H2SO4 and 0.5 M NaOH solutions. The metallic deposits were prepared by electrolysis at constant current ...
Methanol Oxidation in Alkaline Medium Using PtIn/C Electrocatalysts
(Springer, 2016-11-01)
Pt/C and PtIn/C with atomic ratios of 90:10, 70:30, and 50:50 were investigated for methanol electro-oxidation in alkaline media by using cyclic voltammetry (CV), chronoamperometry (CA), and direct methanol alkaline fuel ...
