Sonoelectrochemistry – an emerging area

Ultrasonic (US) radiation in liquid media is known to produce chemical effects with significant acceleration of reaction rates. Influence on US on electrochemical processes-sonoelectrochemistry-is not totally new. Extensive studies have been reported on the relaxation phenomena and structure of electrolyte solutions, with the help of ultrasounds. However, investigations on the influence of ultrasound on electrode reactions and electrosynthesis are of recent origin. Ultrasonic radiation, known to produce cavitation and microstreaming phenomena in liquid media, has resulted in very high current densities and a modified pattern of product yields during electrochemical reactions. Thus, interfacing ultrasound with electrochemistry appears to hold a lot of potential and the field of sonoelectrochemistry is set to make new strides. Recent investigations in this area carried out in our laboratories and elsewhere are reviewed in this communicatio
