“…ZnO, BaTiO 3 , MoS 2 , MoSe 2 , PVDF, and PbTiO 3 have been reported to exhibit piezoelectric properties. Researchers have combined piezoelectric materials and photocatalysts in one system to accelerate the charge transfer and separation for enhanced photocatalytic performance . Particularly, piezoelectric materials could generate internal electric fields to separate photogenerated electrons and holes in photocatalysts with opposite charges, consequently improving photocatalytic activity.…”

“…sound waves of frequency above 20 kHz, can benefit photocatalysis in multiple ways, from promoting the synthesis of photocatalysts with tailored physicochemical properties to enhancing reaction efficiency via synergisms between ultrasound and light irradiation in sonophotocatalysis [2]. Moreover, piezo-enhanced photocatalysis has recently emerged as a promising external field-enhanced photocatalytic technology [3,4] that can significantly promote the efficiency of both downhill and uphill reactions [5][6][7].…”
