Optimization Studies of Photocatalytic Tungsten-Doped Titania Coatings Deposited by Reactive Magnetron Co-Sputtering
In this article we investigate the structural and photocatalytic properties of W-doped titanium dioxide coatings. TiO2-W thin films were deposited onto glass slides by reactive magnetron co-sputtering. The properties of the films were analyzed using such techniques as XRD, Raman spectroscopy, EDX, TEM, and surface profilometry. The photocatalytic properties of the coatings were assessed using t...
متن کاملColloidal Crystals-Self-Assembly of Monodispersed Colloidal Particles-
Colloidal crystals are three-dimensionally periodic lattices assembled from monodispersed spherical colloids. The ability to crystallize spherical colloids into spatially periodic structures has enabled interesting and often useful functionality not only from the constituent colloidal particles, but also from the long-range order exhibited by these periodic structures. A variety of methods by w...
متن کاملStructural formation and photocatalytic activity of magnetron sputtered titania and doped-titania coatings.
Titania and doped-titania coatings can be deposited by a wide range of techniques; this paper will concentrate on magnetron sputtering techniques, including "conventional" reactive co-sputtering from multiple metal targets and the recently introduced high power impulse magnetron sputtering (HiPIMS). The latter has been shown to deliver a relatively low thermal flux to the substrate, whilst stil...
متن کاملHydrogen peroxide route to Sn-doped titania photocatalysts
UNLABELLED BACKGROUND The work aims at improving photocatalytic activity of titania under Vis light irradiation using modification by Sn ions and an original, simple synthesis method. Tin-doped titania catalysts were prepared by thermal hydrolysis of aqueous solutions of titanium peroxo-complexes in the presence of SnCl4 or SnCl2 using an original, proprietary "one pot" synthesis not employi...
متن کاملNitrogen-doped titania nanosheets towards visible light response.
Nitrogen-doped titania nanosheets with visible light response were synthesized by exfoliating a layered titanate with homogeneous nitrogen doping.
