Synthesis of nanometer-size Bi3TaO7 and its visible-light photocatalytic activity for the degradation of a 4BS dye

A general, one-step and template-free synthesis of sphere-like zinc ferrite nanostructures with enhanced photocatalytic activity for dye degradation

“…4d, the absorption edges of the ZnFe 2 O 4 nanospheres and the ZnFe 2 O 4 nanoparticles are around 750 and 776 nm, respectively. The band gap (Eg) of the samples can be evaluated from the following equation [23]:…”

Single-crystalline Bi5O7NO3 nanofibers: Hydrothermal synthesis, characterization, growth mechanism, and photocatalytic properties

“…BiOCl [14], Bi 3 TaO 7 [15], Bi 2-MoO 6 [16,17], Bi 2 WO 6 [18], BiVO 4 [19], BiOX (X = F, Cl, Br, I) [20], Na 0. 5 Bi 1.5 O 2 Cl [21] and Bi 5 O 7 I [22]) have received recent interest due to their high chemical stabilities and visible-light photocatalytic activities, both of which have been ascribed to their unique layered structures.…”

“…The product was then collected, washed and dried at 60°C. For comparison, the nanosized Bi 3 TaO 7 catalyst was prepared by according to our previous study [15].…”

Effectiveness of photodecomposition of rhodamine B and malachite green upon coupled tricomponent TiO2(Anatase-Rutile)/ZnO nanocomposite

“…These ultra-reactive species associated with oxygen are able to achieve a complete mineralization of organic pollutants into carbon dioxide, water and other non-toxic products [35][36][37][38][39]. Among various semiconductor photocatalysts for environment purifi cation, titania appears to be the most promising and important one due to its stable physical and chemical characteristics, unique electronic properties, strong oxidizing power, non-toxicity and low price [40][41][42][43][44][45]. However, the wide band gap of TiO 2 (>3.0 eV) and the high recombination rate of the photoinduced electronhole pairs formed in photocatalytic processes limit the effi ciency of the photocatalytic degradation of toxicants.…”
