Recent electrochemical studies of the cathodic reduction of hydrogen peroxide (H 2 O 2 ) on silver electrodes in acidic electrolyte (HClO 4 ) revealed a novel autocatalytic reaction path. Adsorbed hydroxyl groups, OH ad , were proposed to act as the

The role of the ammonium ion during iron deposition in a ferrous sulfate bath was investigated. When cathodic polarizations were performed in a solution of 0.02 M FeSO4 at pH 3, quartz crystal microbalance measurements showed that the presence of amm

Electrochemical microprobes for monitoring of the electrochemical conditions inside recesses are needed to better understand how localized corrosion and other charge-transfer processes occur in confined spaces. The electrode potential distribution ca

This paper demonstrates the use of the new Iyer/Pickering/Zamanzadeh/Al-Faqeer (IPZA) analysis to determine the effect of the iodide surface coverage (θI−) on the hydrogen surface coverage (θH) and the rate constants of the hydrogen evolution rea

The cathodic reduction of copper(II) in an electrolyte comparable to technical conditions (2.2M H2SO4 + 0.3M CuSO4) is markedly affected by the presence of small concentrations of halide ions. Chloride ions accelerate the reaction, while it is slowed

The cathodic reduction of copper(II) is studied in the absence and in the presence of chloride ions (1×10−3≤cCl≤8×10−3 M) in an electrolyte that is comparable to galvanic copper baths (2.2 M H2SO4+0.3 M CuSO4). Experiments conducted with th

A 70% Sn–30% Zn layer is deposited from a neutral non-cyanide bath. Scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS) show that it is composed of Sn and Zn phases. By use of an electrochemical quartz crystal microbal

Many electrochemical processes contain more than one charge transfer step. If one of these steps leads to a mass change of the working electrode one can use the electrochemical quartz crystal microbalance (EQCM) in situ to determine the rate of this

Recently, it was shown that the reduction of hydrogen peroxide on silver in perchloric acid proceeds in two parallel paths. The normal reduction is observed at an overpotential of − 1.5 V whereas a second reduction reaction occurs at a significantl
