Nanoscale TiO2 films and their application in remediation of organic pollutants

“…[28,30,[42][43][44][45][46][47], co-doping of metals/nonmetals with other metals/non-metals [48][49][50][51][52], coupling with carbonaceous nanoscale materials (fullerene (C 60 ), carbon nanotubes (CNTs) and graphene) [53][54][55][56][57][58][59] and metal oxides (WO 3 [60], [61], SnO 2 [62], MoO 3 [63], SiO 2 [64]), as well as capping (coating of one semiconductor or metal nanomaterial on the surface of another semiconductor or metal nanomaterial core) of TiO 2 [65,66]. Coupling of narrowband semiconductors with TiO 2 to form heterojunction nanostructures (LaVO 4 /TiO 2 [67], Bi 2 WO 6 /TiO 2 [68], boron doped diamond-TiO 2 [69]) as well as rutile-anatase heterojunction [70][71][72][73][74][75][76] have also been investigated to enhance photocatalytic activity of TiO 2 in visible light.…”

Removal of tetracycline from aqueous solution by a Fe3O4 incorporated PAN electrospun nanofiber mat

“…Various works have been reported for composite nanofibers application in water treatment, such as heavy metal adsorption (Taha et al, 2012), photocatalytic degradation of organic pollutants (Liu et al, 2012c) and disinfection (Qu et al, 2013). However, to our best knowledge, little work has been done on the electrospun composite nanofibers for TC removal.…”

Solar photocatalytic activity of chemical solution-prepared barium tungstate nanostructures

“…Generally, the pH of the solution is an important parameter influencing the degradation efficiency of some organic compounds in the photocatalytic process and it is also an important operational variable in actual wastewater treatment [37]. The variation of solution pH changes the surface charge of photocatalyst particles and shifts the potentials of catalytic reactions.…”
