Incorporation of 12-Tungstophosphoric acid in Titania spheres and fabrication of core-shell Polyoxotungstate/Titania nanostructures
نویسندگان
چکیده مقاله:
Core-shell 12-tungstophosphoric acid/TiO2 (HPW/TiO2) nanoparticles at 10 and 20% of HPW have been synthesized by simple in-situ sol- gel method. Characterization of the samples was carried out by X-ray diffraction (XRD), Scanning electron microscopy (SEM), Fourier transform infrared (FTIR). The X-ray diffraction patterns of as prepared solid samples, indicated characteristic peaks of titania with additional peaks concerning to HPW in a very low intensities. This result in addition to the FTIR and SEM - EDX analysis data confirmed incorporation of HPW / TiO2 nanostructure in spherical morphology with a particle size of around 25 nm.

متن کاملFabrication and Optical Behaviors of Core–Shell ZnS Nanostructures
Novel core-shell nanostructures comprised of cubic sphalerite and hexagonal wurtzite ZnS have been synthesized at 150°C by a simple hydrothermal method. The results of HR-TEM and SAED investigation reveal that the cores of hexagonal wurtzite ZnS (ca. 200 nm in average diameter) are encapsulated by a shell of cubic sphalerite ZnS. The FE-SEM image of the nanomaterials shows a surface tightly pac...
متن کاملSynthesis and characterization of noble metal–titania core–shell nanostructures with tunable shell thickness
Core-shell nanostructures have found applications in many fields, including surface enhanced spectroscopy, catalysis and solar cells. Titania-coated noble metal nanoparticles, which combine the surface plasmon resonance properties of the core and the photoactivity of the shell, have great potential for these applications. However, the controllable synthesis of such nanostructures remains a chal...
متن کاملControllable fabrication of PS/Ag core-shell-shaped nanostructures
In this paper, based on the previous steps, a facile in situ reduction method was developed to controllably prepare polystyrene/Ag (PS/Ag) core-shell-shaped nanostructures. The crucial procedure includes surface treatment of polystyrene core particles by cationic polyelectrolyte polyethyleneimine, in situ formation of Ag nanoparticles, and immobilization of the Ag nanoparticles onto the surface...
