“…The developed perovskites/polymer composites exhibited high energy bandgap ranging between 3.8 eV and 3.9 eV. The energy bandgap value obtained in the case of the LaTiO3 composite is in line with that already reported for the LaTiO3 crystal which was equal to 3.46 eV 33 . Remarkably, the energy bandgaps of the synthesized photocatalysts weren't affected by the variation of the perovskites mass percentages into the neat polymer (See Table 4).…”

“…In fact, titanate perovskites are thermically stable and are characterized by a remarkable high corrosion resistance which is suitable to their photocatalytic applications 31 . Moreover, lanthanum perovskites constituted by lanthanum at A site and transition element at site B, were involved in their powdered forms, previously in many catalytic reactions such as the degradation of methylene blue, neutral red, rhodamine B and congo red 32 and atrazine 33 . To support the choice of Acid Black as a model pollutant for the monitoring of the photocatalytic ability of the different developed composites, it has to be noticed that this dye can be found in textile industries effluents and to its attested harmful carcinogenic effects totally support the ongoing efforts to develop efficient methods to mineralize this dye 34,35 .…”

Recently, many researchers have focused their attentions on associating perovskites with polymers in order to enhance their processability and rigidity while protecting their interesting environmental properties. Therefore, this work reports the successful development of two different perovskites/polymer composites via a simple, rapid, low-cost and eco-friendly photopolymerization process under mild visible Light Emitting Diode LED@405nm irradiation. The as-synthesized composites exhibit excellent photocatalytic activity towards the removal of the Acid Black dye from water, reaching approximatively 95% under just 30 min of UV light irradiation. The fruitful hybridization between the perovskite and the acrylate monomer allowed the collect and reuse of this photocatalyst for several successive cycles without external usual time-consuming methods. Furthermore, the new asfabricated shaped materials were fully characterized by numerous characterization techniques including SEM, TEM, EDX, DRX, AFM, DMA and ATG which have verified on one side the successful immobilization of the perovskites into the polymer and the structural stability of the photocatalysts after hybridization and in the other side the high rigidity and thermal stability of the obtained molded composites.

“…In another study, Ag nanoparticle was used to decorate LaTiO 3 for the degradation of pesticide in water. The authors (Shawky et al, 2020) observed an improvement in the surface texture as observed from the morphological analysis. The composite demonstrated an enhancement in light absorption and reduced recombination rate as compared to the pure LaTiO 3 ; as a result, complete degradation of atrazine pollutant within 40 min of irradiation was observed.…”

Meeting the global challenge of water availability necessitates diversification from traditional water treatment methods to other complementary methods, such as photocatalysis and photoelectrocatalysis (PEC), for a more robust solution. Materials play very important roles in the development of these newer methods. Thus, the quest and applications of a myriad of materials are ongoing areas of water research. Perovskite and perovskite-related materials, which have been largely explored in the energy sectors, are potential materials in water treatment technologies. In this review, attention is paid to the recent progress in the application of perovskite materials in photocatalytic and photoelectrocatalytic degradation of organic pollutants in water. Water treatment applications of lanthanum, ferrite, titanate, and tantalum (and others)-based perovskites are discussed. The chemical nature and different synthetic routes of perovskites or perovskite composites are presented as fundamental to applications.

“…Even trace pesticides can persist and have a massive impact on the ecosystem and human health. Semiconductor photocatalysis technology has also been applied to the field of pesticide degradation, which has chemical stability and anti-biodegradation [ 90 , 91 ]. The semiconductor materials for photocatalytic degradation of pesticides are mainly concentrated in various metal oxides (such as TiO 2 and ZnO) [ 92 ].…”
