Photocatalytic nanocomposite anatase–rutile TiO2 coating

Abstract

Nanocomposite TiO2 coatings of mixed anatase-rutile crystalline polymorphs with strong adherence to glass substrates were prepared via spray-plasma deposition method. The rutile content was varied between 0 and 30 mol%. The coating showed an enhanced photocatalytic activity towards cefixime antibiotic decomposition in aqueous solutions under UVA (=365 nm) light illumination. The activity significantly increased after the rutile phase formation, suggesting a synergetic effect of the two-component solids.

Recent advances in removal of pharmaceutical pollutants in wastewater using metal oxides and carbonaceous materials as photocatalysts: a review

“…and initial concentration of amoxicillin of 17 mg L −1 under 240 min of solar irradiation due to a synergistic effect. In addition, several other studies have also been reported using TiO 2 , [157][158][159] and supported TiO 2 160 on the photocatalytic remediation of amoxicillin. 3.2.1.2 ZnO and other metal oxides.…”

“…These studies showed 84.12% degradation of amoxicillin after 240 min under optimum conditions of pH 9.5, catalyst dose of 1.5 g L −1 and initial concentration of amoxicillin of 17 mg L −1 under 240 min of solar irradiation due to a synergistic effect. In addition, several other studies have also been reported using TiO 2 , 157–159 and supported TiO 2 160 on the photocatalytic remediation of amoxicillin.…”

“…3.5.6 Heterojunction, Z-and S-scheme-based composites. Ni-doped ZnO/MWCNTs were tested for complete degradation of norfloxacin corresponding to initial concentrations in mg L −1 (time in min) of 10 (30), 20 (60), 50 (120), 100 (160) and 10 (40), 20 (70), 50 (150), 100 (200) under visible and UV radiation, respectively. 400 The findings also suggested that MWCNTs can act as a charge transfer channel for accelerating electron transfer between Ni and ZnO nanoparticles.…”

“…Hence, it is necessary to conduct a large amount of research on the treatment and removal of amoxicillin from wastewater using a variety of photocatalysts before discharging it into the natural aquatic environment. 149–216…”

Photocatalytic degradation of ammonia nitrogen using a Z-type nano-TiO2/LaMnO3 heterojunction

“…27 There are also diffraction peaks of rutile TiO 2 crystals (JCPDS: 21-1272) at 27.51, 36.11 and 54.41, corresponding to the crystal faces (110), ( 101) and (111), respectively. 28 Therefore, its structure has a mixed crystalline phase (anatase and rutile). The overall peak positions of LMO are essentially the same as that of the standard card (JCPDS: 01-072-6619), 29,30 The results show that the prepared lanthanum manganate powder has a hexagonal perovskite structure.…”
