The ferroelectric semiconductor material PbTiO3 exhibits remarkable spontaneous polarization and photoelectric properties,positioning it as a promising polar photocatalyst.The internal electric field of ferroelectrics can separate photocarriers and enhance the catalytic per-formance of photocatalysts.Moreover,when combined with other semiconductors,PbTiO3 contributes to the construction of a depolarization field,extending the cat-alytic applications of PbTiO3 catalysts.PbTiO3 exhibits optical absorption,semiconductor,and piezoelectric prop-erties.Its piezoelectric polarization field enhances charge separation,modulates band structure,surface charge con-duction,and heterojunction interface charge conduction,thereby amplifying photocatalytic activity.This paper begins by examining the structure,properties,and prepa-ration methods of PbTiO3.Subsequently,it delves into the optimization of PbTiO3's structure and performance,exploring applications in photocatalysis as a ferroelectric photocatalyst.Emphasis is placed on the detailed discus-sion of surface modification,heterostructure formation,and ferroelectric polarization of PbTiO3 ferroelectrics.These aspects are thoroughly explored for their role in regulating activity and optimizing the performance of photocatalysis and photopiezoelectric catalysis.In conclusion,the paper addresses the current research status of PbTiO3 ferroelec-tric materials and highlights the challenges that lie ahead.The intention is to provide valuable references for the ongoing research in PbTiO3 ferroelectric materials.
