Sonopotential: a new concept in electrochemistry

摘要

The application of ultrasound to a solution in contact with a semiconductor working electrode leads to a change in its open circuit potential, that is, to the appearance of a sonopotential sensitive to both ultrasonic power and solution composition.rnThe use of TiO_2 particles as heterogeneous photocatalysts has been proposed for 20 years as a viable way of removing contaminants from either water or air, constituting one of the incipient technologies known as advanced oxidation processes. Another of such technologies takes advantage of the enhanced reactivity linked to various physical and chemical effects of ultrasound.
