However, this high dielectric/ferroelectric material is only active in UV light (band gap 3.2 eV), which reduces the photocatalytic degradation performance. To make barium titanate more suitable for photocatalysis, the surfaces of the powders can be modified to broaden the absorption band. In this paper, various strategies for improving photocatalysis of barium titanate for removing organic pollutants (mostly dyes and drugs) from water/wastewater are critically reviewed. They include modifying the sizes and morphologies of the particles by varying the reaction times and synthesis temperatures, doping with metals/non-metals, loading with noble metal NPs (Ag and Au), and fabrication of heterojunction photocatalysts (conventional type II and Z-scheme). The current challenges and possible future directions of BaTiO3-based materials are also discussed. This comprehensive review is expected to advance the design of highly efficient BaTiO3-based materials for photocatalytic applications in water/wastewater treatment.Disposal of noxious plant residues is a challenge for farmers and land management dealing with contaminated biomasses. Recent studies confirm the potential threat of transferring toxic plant constituents like pyrrolizi
