摘      要：Barium titanate(Ba TiO_(3)),a dielectric/ferroelectric semiconductor with perovskite structures is the most widely used photocatalyst in the field of environmental applications due to its low-cost,chemical stability,and *** types and forms of Ba TiO_(3)have shown their great potential toward the significant photocatalytic reactions owing to the several beneficial properties,including appropriate band positions,high oxygen vacancies,multiple crystal structures,the feasibility of size and morphology tailoring,spontaneous polarization,rapid migration of photogenerated charge carriers,and band ***,the large band gap and recombination of photogenerated charge carriers limit the overall photocatalytic efficiency of Ba TiO_(3).These difficulties can be further overcome by modifying the electronic band structure of Ba TiO_(3)to broaden its absorption to the visible region of the ***,this review encompasses various strategies,including modification of sizes and morphologies of particles by varying the reaction time and synthesis temperature,doping with non-metals/metals,loading with noble metals,and forming heterojunctions for enhancing the photocatalytic activities of Ba TiO_(3)-based photocatalysts possessing the effective capability of charge carrier separation,trapping and their transfer to the surface of ***,this review highlights the photocatalytic applications of Ba TiO_(3)-based photocatalysts along with the proposed mechanism in dyes/drugs degradation,H_(2)production,and bacteria killing.
