The application of ultrasound with electrochemistry in organic chemistry (known as sonoelectrochemistry) accelerates the activation process chemical reactions. This hybrid technology enhances electrical efficiency and modifies increases product yield. Moreover, it facilitates mass transfer phenomena processes cleaning, degassing, electrode surfaces; maintains higher current densities for effici...

As reported in the literature, several factors, such as scattering cross sections, polarisability and wavelength suitability, contribute to increased SERS enhancement. In general, the advantage of surface-enhanced Raman scattering (SERS)-active Ag nanoparticles (NPs) is their higher SERS enhancement over Au NPs because the molar extinction coefficient of the Ag NPs is the highest of its kind am...

This paper presents sonochemically deposited polypyrrole films and their characteristics of adhesion on substrate with related to the surface roughness and morphology by comparing to the conventional films deposited electrochemically. In particular, the use of high frequency sonication (500 kHz) for sonoelectrochemical deposition of polypyrrole was reported for the first time. Chronocoulometry ...

BACKGROUND Perfluorocarboxylic acids (PFCAs) are emerging pollutant and classified as fully fluorinated hydrocarbons containing a carboxylic group. PFCAs show intensively resistance against chemical and biological degradation due to their strong C-F bond. The Sonoelectrochemical mineralization of the synthetic aqueous solution of the perfluorooctanoic acid (PFOA) on Ti/PbO2 anode was investigat...

Platinum group metals, such as Pd and Pt, found in three-way catalyst converters were recycled a two-step method: hydrodynamic cavitation followed by sonoelectrochemical dissolution. High shear forces obtained using convergent nozzle with throat diameter of 0.2 mm, feeded plunger pump at pressure 60 MPa. Cavitating submerged jets acted locally on the water dispersed waste catalyst. As-obtained ...

Textile industry effluents contain reactive dyes that may harm our receiving waters. A typical reactive blue (RB) 19 dye is frequently detected in significant concentrations in textile industry effluents. Such dyes have generally shown resistance to decomposition and tend to persist in the environment for long periods and multiply the impacts to water and environment. Therefore, the present inv...

In recent years, combinatorial methods have attracted a great deal of attention. Among them, sono-combining techniques have shown a significant potential as an economic technology applicable and environment-friendly technology for wastewater treatment. In this study, Sono Electrochemical SE, Sono Photo Electrochemical SPE and Sono Photo Electro Catalytic SPEC techniques were investigated for de...
