A Study on the Modification of Conventional Electrochemical Crystallization under Sonication: The Phenomena of Secondary Nucleation

Abstract

An understanding of the nucleation mechanism involved in the sonoelectrochemical synthesis of copper from sulfate bath is reported here. These explanations include the analysis of sono-chronoamperometric current transients and atomic force microscopy.The results indicate that ultrasound induces secondary nucleation by breakage of the existing primary nuclei in addition to the primary nucleation. The understanding of the sonoelectrochemical mechanisms clarifies a few unclear issues. It could possibly allow for the better design of sonoelectrochemical synthesis.
