Figure 3. (A) Schematic of cavitation effect of Ba_xSr_1-xTiO₃ ferroelectric particles in the presence of ultrasound. (B) Effect of Curie temperature T_c on polarization^[62]. (C) Hydrogen evolution reaction (HER) free energy diagrams at zero potential over diverse Co-In₂Se₃ heterojunctions. (D) By binding AuNRs with ferroelectric PTO pellets, which possess greater remanent electric dipole moments, the hot charges produced on the plasma particles are able to pump into the ferroelectric material and actuate the photocatalytic HER^[72]. (E) Ferroelectric membrane for water purification to reject arsenic^[75]. (F) Schematic of the markedly improved piezoelectric photocatalytic ability of BTO nanowires to degrade the environmental aspects of an organic dye^[82]. T_c: Curie temperature; AuNRs: gold nanorods.
