摘要

Due to urban expansion and rapid industrialization, water pollution significantly increases which gives necessity of efficient water purification technologies. ABO3 pervoskites are good for the degradation of organic pollutants because of their unique photocatalytic properties. This review explores the modification strategies of ABO3 perovskites, which focus on enhancing their photocatalytic activity for water treatment applications. It includes the advanced fabrication techniques, Site-Specific Doping At the A, B and O and the formation of nanocomposites to improve photogenerated charge Carrier Separation. The electronic and structural properties of ABO3 perovskites have introduced the foreign ions at A and B sites. ABO₃ systems show significant performance gains, such as > 90% degradation of Rhodamine B or methylene blue within 60–120 min and up to 2–3-fold increases in rate constants compared to pristine perovskites. Co-catalysts and the advanced synthesis improve the performance of these material and also emphasizes the critical roles of heterojunction formation and nanostructure design in intrinsic limitations. The development of efficient, scalable and eco-friendly photocatalytic systems that positioning ABO3 pervoskite for next generation water purification technologies.
