ZnFe2O4 nanoparticle: Synthesis and photocatalytic activity under UV-vis and visible light
In the present work, the ZnFe2O4 nanoparticle has been successfully synthesized. The obtained sample was characterized by X-ray diffraction (XRD), emission scanning electron microscopy (FE-SEM) and its optical property was examined by UV-Vis spectrophotometer. FE-SEM revealed that the particle size of the ZnFe2O4 of about 47 nm was synthesized. The photocatalytic performance under UV-Vis and vi...
متن کاملS-doped mesoporous nanocomposite of HTiNbO5 nanosheets and TiO2 nanoparticles with enhanced visible light photocatalytic activity.
The S-doped mesoporous nanocomposite (S-TNT) of HTiNbO5 nanosheets (NSs) and anatase TiO2 nanoparticles (NPs) with exposed {101} facets has been successfully synthesized by first mixing freeze-dried HTiNbO5 NSs with titanium isopropoxide and then calcination with thiourea in air. The exposed anatase {101} facets can act as a possible reservoir of the photogenerated electrons, yielding a highly ...
متن کاملExceptional visible-light-driven photocatalytic activity over BiOBr-ZnFe2O4 heterojunctions.
An ultrasound-assisted, precipitation-deposition method has been developed to synthesise visible-light-responsive BiOBr-ZnFe(2)O(4) heterojunction photocatalysts. The heterojunctions with suitable BiOBr/ZnFe(2)O(4) ratios have a fascinating micro-spherical morphology and exhibit exceptional photocatalytic activity in visible-light degradation of Rhodamine B.
متن کاملProperty Characterization and Photocatalytic Activity Evaluation of BiGdO3 Nanoparticles under Visible Light Irradiation
BiGdO₃ nanoparticles were prepared by a solid-state reaction method and applied in photocatalytic degradation of dyes in this study. BiGdO₃ was characterized by X-ray powder diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy, Brunauer-Emmett-Teller, UV-Vis diffuse reflectance spectroscopy and transmission electron microscopy. The results showed that BiGdO₃ crystallized ...
متن کاملPhotocatalytic Activity with Visible Light Irradiation
Titanium dioxide (TiO2) was doped with the combination of several metal ions including platinum (Pt), chromium (Cr), vanadium (V), and nickel (Ni). The doped TiO2 materials were synthesized by standard sol-gel methods with the doping levels of 0.1 to 0.5 atom-%. The resulting materials were characterized by the X-ray diffraction (XRD), BET surface-area measurement, Scanning Electron Microscopy ...
