Scalable Production of Monolayer Shell(Pt)@Core(Pd) Nanoparticles by Electroless Cu UPD for Oxygen Reduction Reaction
Electrocatalysis - Tập 12 - Trang 127-136 - 2021
In this article, we discuss an electroless under potential deposition (UPD) method to synthesize core@shell monolayer nanoparticles in bulk quantities. In this electroless UPD method, potential is controlled and maintained in the UPD region by a redox couple. This electroless path enables the production of core@shell monolayer catalysts on any type of support, unlike the conventional UPD, where po...... hiện toàn bộ

Applicability of Electroanalysis for Monitoring Oxalic Acid (OA) Concentration During its Electrochemical Oxidation at Different Electrode Materials
Electrocatalysis - Tập 4 - Trang 267-273 - 2013
The electrochemical oxidation (EO) of oxalic acid (OA) has been studied in acidic media at Ti/PbO2, highly boron-doped diamond (BDD), Pt, and graphite electrodes by linear polarization and galvanostatic electrolyses applying a current of 60 mA cm−2. The concentration of OA during EO was monitored by differential pulse voltammetry (DPV) using glassy carbon electrode and the results were also confir...... hiện toàn bộ
The Electrochemical Dissolution of Noble Metals in Alkaline Media
Electrocatalysis - Tập 9 - Trang 153-161 - 2017
In this study, the electrochemical transient dissolution of polycrystalline silver, gold, iridium, palladium, platinum, rhodium, and ruthenium is examined in 0.05 M NaOH alkaline electrolyte as a function of electrode potential. An inductively coupled plasma mass spectrometer connected to an electrochemical flow cell is used for online detection of the metals dissolution rates. Broad potential win...... hiện toàn bộ
Electrochemical Detection of Glucose in Beverage Samples Using Poly(3,4-ethylenedioxythiophene)-Modified Electrodes with Immobilized Glucose Oxidase
Electrocatalysis - Tập 9 Số 3 - Trang 380-387 - 2018
We developed two glucose biosensors based on poly(3,4-ethylenedioxythiophene) (PEDOT) and polyacrylic acid (PAA) doped with poly(4-lithium styrenesulfonic acid) (PSSLi) or PEDOT and anthranilic acid (AA) doped with poly(4-styrenesulfonic acid) (PSSH). The first one was already mentioned in literature in similar configurations; however, the second one has not been described before. The glucose oxid...... hiện toàn bộ

The Effect of Noncovalent Interactions on the HOR, ORR, and HER on Ru, Ir, and Ru0.50Ir0.50 Metal Surfaces in Alkaline Environments
Electrocatalysis - Tập 3 - Trang 221-229 - 2012
The role of noncovalent interactions in the hydrogen oxidation reaction (HOR), oxygen reduction reaction (ORR), and hydrogen evolution reaction (HER) on Ru, Ir, and Ru0.5Ir0.5 electrodes is studied in alkaline solution containing K+, Li+, and Ba2+ cations. We found that noncovalent interaction between hydrated cations and covalently bonded OHad increases in the same order as specific charge densit...... hiện toàn bộ
A Simple Method to Establish the Relationship Between the Equilibrium Polarization Resistance and the Elementary Kinetic Parameters of an Electrocatalysed Reaction
Electrocatalysis - Tập 9 - Trang 409-415 - 2017
A simple and rigorous methodology to establish the relationship between the faradaic equilibrium polarization resistance of an electrocatalytic reaction with the elementary kinetic parameters involved in the reaction mechanism is proposed. It was derived through an alternative method, which avoided the differentiation of the corresponding current-overpotential dependence. This formalism includes t...... hiện toàn bộ
Effect of Gold Modification with 3-Mercaptopropionic Acid, Cysteamine and Gold Nanoparticles on Monoethanolamine Electrooxidation
Electrocatalysis - Tập 7 - Trang 79-86 - 2015
In this work, a gold electrode modified with self-assembled layers (SAMs) composed of 3-mercaptopropionic acid, cysteamine and gold nanoparticles was prepared. The electrode with SAMs endowed with gold nanoparticles gave the high catalytic effect for monoethanolamine (MEA) electrooxidation in solution at pH 7. For this novel sensor, a linear relationship between the current response of MEA at the ...... hiện toàn bộ
