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) ...
Evidences of CO spillover at a Pt/Pd bimetallic interface during the formic acid oxidation reaction
(Elsevier Science Sa, 2019-06)
The surface diffusion (spillover) through the intermetallic Pt/Pd junction of adsorbed CO (CO ad ) during the formic acid electrooxidation reaction (FAO) was analyzed on a bimetallic Pt/Pd electrode by chronoamperometry ...
Electrochemical synthesis of Rh-Pd bimetallic nanoparticles onto a glassy carbon surface
(Elsevier Science Sa, 2016-10)
Rh-Pd bimetallic nanoparticles were prepared successfully by sequential electrodeposition on a glassy carbon (GC) substrate using single potentiostatic pulses. The generated particles were characterized by ex-situ atomic ...
Detection of Cd (II) and Pb (II) by anodic stripping voltammetry using glassy carbon electrodes modified with Ag-Hg and Ag-Bi bimetallic alloyedDetección de Cd (II) y Pb (II) por voltamperometría de separación anódica utilizando electrodos de carbono vidriosos modificados con aleación bimetálica Ag-Hg y Ag-Bi

Thermodynamic Guidelines for the Design of Bimetallic Catalysts for Oxygen Electroreduction and Rapid Screening by Scanning Electrochemical Microscopy. M−Co (M: Pd, Ag, Au)
(American Chemical Society, 2005-01)
We propose guidelines for the design of improved bimetallic (and related) electrocatalysts for the oxygen reduction reaction (ORR) in acidic media. This guide is based on simple thermodynamic principles assuming a simple ...
Ordered Array Electrodes Fabricated by a Mask-Assisted Electron-Beam Method as Platforms for Studying Kinetic and Mass-Transport Phenomena on Electrocatalysts
(Wiley-VCH Verlag, 2018-09)
This work describes a method for fabrication of extensive ordered arrays of microelectrodes with varied geometries, surrounded either by an insulating surface of poly(methyl methacrylate) (PMMA) or by a conductive material ...
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 ...
Electroactive copper (II) bimetallic self-assembled multilayers on Si (100)
(2012)
Silicon (100) surfaces were modified by reacting 4-aminopyridine and Si–Cl bond. These surfaces were further used for tethering copper bimetallic complexes and growing monolayers and multilayers by changing the axial ...
Food safety control of zeranol through voltammetric immunosensing on Au?Pt bimetallic nanoparticle surfaces
(Royal Society Of Chemistry, 2014-06)
This study reports an accurate and sensitive strategy for zeranol (ZER) determination in bovine urine samples. ZER is a mycotoxin widely used as a synthetic growth promoter in the livestock production whose residues could ...
