Bismuth titanate based photocatalysts for degradation of persistent organic compounds in wastewater: A comprehensive review on synthesis methods, performance as photocatalyst and challenges

Type, Sources, Methods and Treatment of Organic Pollutants in Wastewater

“…Inexpensive, non-noble transition metals or their oxides supported in carbon nanotube has been reported for treatment of POPs. Bismuth-based nanocomposites [84], copper-reduced graphene oxide electrode [85], boron-doped diamond [86], with different boron and substrate silicon or niobium content [87] have indicated to be an efficient technology for treating POPs wastewater.…”

Sonochemical preparation and characterization of Sm‐doped GO/KSrPO4 nanocomposite photocatalyst for degradation of methylene blue dye

“…Both these species help to degrade the methylene blue dye and produce harmless products (Equations 4 and 5) (Moradi, Hasanvandian, et al, 2021). Another major factor that play role in the photocatalytic property of the synthesized GO/KSrPO 4 :Sm nanocomposite photocatalyst is its heterostructure (Kallawar et al, 2021). In the synthesized photocatalyst, the three types of materials, that is, GO, KSrPO 4 , and Sm, are combined to form a heterostructure.…”

Persulfate assisted photocatalytic degradation of tetracycline by bismuth titanate under visible light irradiation

“…[13][14][15] Of the many photocatalytic materials, bismuth-based semiconductors, such as bismuth vanadate, bismuth oxyhalide and bismuth titanate, have been extensively investigated to remove toxic organic pollutants, benefiting from their special electronic structure, morphology and crystal structure. [16][17][18][19] As a type of bismuth titanate compound, Bi 2 Ti 2 O 7 (BTO) with a pyrochlore-type structure is also found to be a promising candidate. [20][21][22] Unfortunately, the inherent drawback that photoinduced electrons and holes are easily recombined leads to low photocatalytic activity, limiting the application of BTO.…”
