Preparation of TiO2 Films with Doping Transition Metals by Sol-Gel Processing and Their Photocatalytic Properties

Preparation, characterization and photocatalytic activity of TiO2 / Methylcellulose nanocomposite films derived from nanopowder TiO2 and modified sol–gel titania

TiO2—methylcellulose (MC) nanocomposite films processed by the sol-gel technique were studied for phocatalytic applications. Precalcined TiO2 nanopowder was mixed with a sol and heat treated. The sol suspension was prepared by first adding titanium tetra isopropoxide (Ti(OPr)4 or TTP) to a mixture of ethanol and HCl (molar ratio TTP:HCl:EtOH:H2O = 1:1.1:10:10) and then adding a 2 wt.% solution ...

EFFECT OF COBALT DOPING ON THE STRUCTURAL AND OPTICAL PROPERTIES OF TiO2 FILMS PREPARED BY SOL-GEL PROCESS

Preparation and characterization of ZnO-TiO2 films obtained by sol-gel method

The sol-gel route has been applied to obtain ZnO-TiO2 thin films. For comparison, pure TiO2 and ZnO films are also prepared from the corresponding solutions. The films are deposited by a spin-coated method on silicon and glass substrates. Their structural and vibrational properties have been studied as a function of the annealing temperatures (400-750 °C). Pure ZnO films crystallize in a wurtzi...

Effects of Cobalt Doping on Optical Properties of ZnO Thin Films Deposited by Sol–Gel Spin Coating Technique

Cobalt (Co) doped Zinc Oxide (ZnO) thin films, containing different amountof Cobalt nanoparticles as the Co doping source, deposited by the sol–gel spin coatingmethod onto glass via annealing temperature at 400˚C, have been investigated by opticalcharacterization method. The effect of Co incorporation on the surface morphology wasclearly observed from scanning electron microscopy (SEM) images. ...
