摘要：

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 H 2 evolution that is achieved by straining a piezoelectric material in aqueous medium.
