Super-hydrophilic SiO2-doped TiO2 photocatalysts for self-cleaning applications
The self-cleaning of glasses can be realized by coating the photoinduced super-hydrophilic nanoporous thin films based on TiO2 photocatalysts via sol–gel route. In this study, a new method to enhance the photocatalytic activity of TiO2 thin films direct coated on the glass was developed by doping SiO2 in the films. The effects of post-annealing and the SiO2 content of TiO2 film on the photocata...
متن کاملSelf-Cleaning Measurement of Nano-Sized Photoactive TiO2
Titanium dioxide (TiO2)nanoparticles have been frequently employed in the environmental treatment and purification purposes as a cheap and highly efficient photocatalyst. A photocatalyst can facilitate the breakdown and removal of a variety of environmental pollutants at room temperature. TiO2 photocatalyst is the best candidatebecause of its strong oxidized ability, non-toxicity and longtherma...
متن کاملTiO2 photocatalysis
It is known that TiO2 exhibits good photocatalytic properties which could be used in various commercial applications such as water and air purification or photo-induced biodegradation of microbes. TiO2 occurs in nature in the form of three crystal polymorphs: anatase, brookite and rutile. For photocatalytic applications only anatase and rutile are of interest, however anatase shows greater phot...
متن کاملPhotocatalytic self-cleaning properties of lanthanum and silver co-doped TiO2 nanocomposite on polymeric fibers
Titania, single-doped and lanthanum-silver co-doped titania nanocomposite were coated on cellulosic and polyacrylonitrile fibers via sol–gel method. The prepared samples were evaluated using x-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive x-ray spectroscopy (EDX), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), photolumines...
متن کاملTiO2 Photocatalysis and Diamond Electrode
This paper presents a simple process for making tellurium (Te) nanoand microtubes of widely varying dimensions with the multiscale processing (MSP) technique. In this process, the Te metal was placed in a borosilicate glass reaction vessel and a fuse quartz substrate was added. Th vessel was evacuated and seal d unde vacuum with a torch. Then, the vessel was heated under a temperatur gradient w...
