Thin Layer Sonoelectrochemistry

ECS Meeting Abstracts, 2014
Ultrasound irradiation of electrodes in a thin electrolyte layer improves heterogeneous electron transfer kinetics.1,2 A bulk fluid irradiated with ultrasonic energy of sufficient intensity generates bubbles by compression and rarefaction. On bubble collapse, extremes of temperature (T ≳ 5000 K) and pressure (P ≳ 10³

Oxidation of phenol in wastewater by sonoelectrochemistry

Chemical Engineering Science, 1996
Abstract Mass transfer was investigated in ultrasonic reactors by means of the electrochemical method (feri-ferro-cyanide couple, under diffusion limitations). This method allowed for the determination of the active zones in the reactor. The oxidation of a model pollutant, phenol, has been carried out in the previously screened reactor, with ...

Sonoelectrochemistry in aqueous electrolyte: A new type of sonoelectroreactor

Electrochimica Acta, 1994
Abstract A new type of sonoelectroreactor is presented. Its most interesting characteristic is the nature of the working electrode which is made up of the immersed titanium horn itself (anode or cathode). The frequency of the home-made reactor is around 20 kHz. The performances of this sonoelectroreactor are tested during the copper electrodeposition.

Electrochemical Quartz Crystal Microbalance Technique in Sonoelectrochemistry

ECS Transactions, 2009
The influence of the experimental conditions on the operation of a quartz crystal microbalance in an ultrasonic field was studied in water and different Cu electrolytes. An increase of the ultrasonic intensity and a decreasing distance between the ultrasonic horn tip and the surface of the quartz resonator caused an increase in signal noise and a ...

Organic Sonoelectrochemistry on Mercury Pool Electrode

Collection of Czechoslovak Chemical Communications, 2000
So far, the influence of sonication on the electrolytic current was studied only at solid or rather miniaturized mercury electrodes. The presented paper reports on sonoelectrochemical experiments at a liquid mercury pool electrode. Two sonoelectrochemical cells have been developed and tested.

Cavitation, Shock Waves and the Invasive Nature of Sonoelectrochemistry

The Journal of Physical Chemistry B, 2005
The invasive nature of electrodes placed into sound fields is examined. In particular, perturbations of the sound field due to the presence of the electrode support are explored. The effect of an electrode on the drive sound field (at approximately 23 kHz) is shown to be negligible under the conditions investigated in this paper. However, scattering of

Iron–chromium alloy nanoparticles produced by pulsed sonoelectrochemistry: Synthesis and characterization

Acta Materialia, 2010
Abstract This study describes synthesis of Fe–Cr alloy nanoparticles by using a method which couples electrodeposition of metals with the employment of high power ultrasound. The production of alloyed nanoparticles was performed using a 20 kHz titanium alloy horn ultrasound generator, a “sonoelectrode” generating short current pulses ( t ON ...

Characterization of Cu–Ni alloy electrodeposition and synthesis of nanoparticles by pulsed sonoelectrochemistry

Materials Chemistry and Physics, 2014
Abstract Binary alloy Cu–Ni nanoparticles were synthesized by sonoelectrochemical technique from aqueous bath in presence of Na-citrate as complexing agent, to allow co-deposition of Cu and Ni. Alloy Pulsed Electro-Deposition (PED) was carried out to study nucleation kinetic and the effects of pH and surfactant on the final product physical and ...

Sonoelectrochemistry: Effects of ultrasound on voltammetric measurements at a solid electrode

Journal of Electroanalytical Chemistry, 1994
Utilization of ultrasound in the field of electrochemistry is rather old. As early as the 1930’s, work on the depolarizing effect of ultrasound was published [1,2]. Increase of mass transport rate by sonication was described first by Bard in 1965 [3].
