The authors have discovered that ultrasonic irradiation of Ni powder increases its activity as a hydrogenation catalyst by >10/sup 5/. In order to probe the origin of this dramatic enhancement, the surface composition has been examined. They find that ultrasonic irradiation of Ni powder causes remarkable changes in particle aggregation, surface morphology, and thickness of the surface oxide coating.

Abstract Examples of sonochemical reactions occuring under heterogeneous conditions are discussed with respect to their mechanism. The activation of a metal surface involves complex phenomena, in

Sonoelectrochemical Synthesis of Nanoparticles

The majority of nanomaterials produced by pulsed sonoelectrochemistry are pure metals, but more recently the syntheses have been extended to include the preparation of nanosized metallic alloys and metal oxide semiconductors.
