“…PW 12 functionalized TiO 2 photocatalysts were prepared by Jin et al [39], who reported that in photodegradation of X-3B, the reactivity of the samples followed the order of POMs weight ratio 30% > 15% > 45%. Lu et al [40] investigated photodegradation of bisphenol A (BPA) on H 3 PW 12 O 40 /TiO 2 photocatalysts. In the studies, 6.3%-PW 12 /TiO 2 , showed the highest efficiency.…”

“…Although many methods were reported, the photocatalytic oxidations process emerged as more significant over the rest. [4][5][6] It is well established that this process dominantly employs TiO 2 semiconductor owing to its high synergetic oxidation strength, zero toxicity, and greater chemical and biological stability. [7][8][9] In spite, it has major obstruction with wider bandgap energy (3.2 eV) and allows the photoactivation to only in the UV spectrum (λ < 390 nm).…”

A well-organised reduced graphene oxide (RGO) and silver (Ag) wrapped TiO2 nano-hybrid was successfully achieved through a facile and easy route. The inherent characteristics of the synthesized RGO-Ag/TiO2 were revealed through crystalline phase, morphology, chemical composition, Raman scattering, UV-visible absorption, and photoluminescence analyses. The adopted synthesis route significantly controlled the uniform formation of silver nanoparticles and contributed for the absorption of light in the visible spectrum through localized surface plasmon resonance effects. The wrapped RGO nanosheets triggered the electron mobility and promoted visible light shift towards red spectrum. The accomplishment of synergised effect of RGO and Ag well degraded Bisphenol A under visible light irradiation with a removal efficiency of 61.9%.

“…It is important to keep in mind that BPA has been decomposed at least by 80 % during 60 min but not totally. The remaining by-products (phenol and quinones [34]) are resistant to further oxidation. Summing it up, we can conclude that the strategy to enhance the photocatalytic activity of SnO 2 -modified TiO 2 deposited on PS-300 can be effected by simultaneous introduction of tin(IV) oxide and titania in the reactor or TiO 2 should be added before SnO 2 .…”

Bisphenol A (BPA) is worldwide used to produce plastics and/or epoxybased foodstuff packages. But it is known that this compound is considered as a quite toxic contaminant due to (1) its similarity to the hormone estrogen and (2) its universal use in many industrial proceses. In our study the photodegradation of BPA stimulated by tin(IV) oxide-modified silica-titania nanocomposites was investigated. The reactions were characterized by the kinetic parameters (pseudo-first constant k 1 0.036-0.0896Á10for non-calcined and 0.0389-0.1144Á10 À2 min À1 for calcined photocatalysts), half-life time t 1/2 7.74-19.23 and 6.66-17.83 min for non-and calcined ones, respectively, allowing to determine both the weight k w and the specific surface area k s of each sample. It will be shown that most SnO 2 -doped silica-titania oxides are more active than commercially available TiO 2 (P-25, Degussa). The best results of BPA removal were obtained for 6 wt% addition of SnO 2 to both calcined and non-calcined photocatalysts.
