Ferroelectric materials exhibit spontaneous electric polarization, generating internal electric fields that modulate band bending at the solid–liquid interface. This intrinsic property enhances charge carrier separation and directs photogenerated electrons and holes toward specific redox sites or cocatalysts. We highlight key studies demonstrating the effectiveness of ferroelectric materials in PEC applications. Electric polarization of BiFeO<sub>3</sub> thin films resulted in controlled enhancement of water oxidation by directly influencing band bending and charge transfer processes. Similarly, BaTiO<sub>3</sub>–TiO<sub>2</sub> core–shell structures with Ni(OH)₂ cocatalysts exhibited improved PEC activity through polarization-mediated charge separation. BaTiO<sub>3</sub> particles also demonstrated enhanced PEC water oxidation and hydrogen evolution in both film and suspension systems due to ferroelectric effects.
