Visible light photocatalytic properties of Bi3.25Eu0.75Ti3O12 nanowires

Chromium-modified Bi 4 Ti 3 O 12 photocatalyst: Application for hydrogen evolution and pollutant degradation

“…This allows for its optical absorbance and photocatalytic properties within the host perovskite structure can be tuned much effectively. For example, Bi 3.25 La 0.75 Ti 3 O 12 nanowires and Bi 3.25 Sm 0.75 Ti 3 O 12 nanostructures are developed, and exhibit visible-light activity towards degradation of organic pollutants [33,34]. Recently, chromium-doped Bi 4 Ti 3 O 12 catalyst, synthesized by first sol-gel process and subsequent calcination treatment of 750 • C, demonstrates photocatalytic production of H 2 under visible-light irradiation [35].…”

Electrospun Cr-doped Bi4Ti3O12/Bi2Ti2O7 heterostructure fibers with enhanced visible-light photocatalytic properties

“…29,30 But these synthesized Bi 4 Ti 3 O 12 bers show relatively low visible-light photocatalytic activity because of their intrinsic properties such as wide band gap (3.0 eV) and low capability for separation of photogenerated charge carriers. To date, although many excellent works have been devoted to enhance the photocatalytic efficiency of Bi 4 Ti 3 O 12 under visible-light irradiation such as doping with metals [31][32][33] and combining with another narrow band gap semiconductor, [34][35][36] the development of high-efficiency visible-light-driven Bi 4 Ti 3 O 12 photocatalysts is still in great demand.…”

Characterization of Vanadium-Doped BaBi4Ti4O15 Prepared by Molten KCl Salt Method

“…Transition metal doping to photocatalyst compound is a strategy to extend the light absorption to the visible [19]. Some metals that have been reported to be used as dopant are La [20], Nb [21], Fe [22], Cr [23], V [24], and Eu [25].…”
