Influence of Morphology and Common Oxidants on the Photocatalytic Property of β-SnWO4 Nanoparticles.

In this paper, we report a simple, cost effective and surfactant-free method for synthesizing different morphology of β-SnWO4 with irregular, spherical, flake-like and leaf-like structures by using sonochemical method followed by calcination. A well dispersed and highly crystalline β-SnWO4 crystallites with various sizes have been prepared. The samples were characterized by using X-ray diffraction (XRD), scanning electron microscope (SEM), UV-vis spectroscopy, particle size and Zeta potential analyser.

Facile Synthesis of Vanadium-Pentoxide Nanoparticles and Study on Their Electrochemical, Photocatalytic Properties.

Vanadium pentoxide (V2O5) nanoparticles were synthesized via an anionic, cationic and non-ionic surfactant-assisted hydrothermal method. The synthesized nanoparticles were characterized by using powder X-ray diffractometer, Scanning Electron Microscope, High Resolution Transmission Electron Microscope and UV-Vis spectroscopy. The experimental results confirm the formation of vanadium pentoxide nanoparticles.
