Piezopotential-Driven Redox Reactions at the Surface of Piezoelectric Materials

Piezocatalysis uses piezopotential to modulate charge carrier energetics (see picture), thus allowing the direct enhancement or suppression of electrochemical reactions that occur at a piezoelectric material/solution interface. Such a direct conversion of mechanical to chemical energy is shown by th...

Zusammenfassung:Piezocatalysis uses piezopotential to modulate charge carrier energetics (see picture), thus allowing the direct enhancement or suppression of electrochemical reactions that occur at a piezoelectric material/solution interface. Such a direct conversion of mechanical to chemical energy is shown by the electrochemical H2 evolution that is achieved by straining a piezoelectric material in aqueous medium.
