Sprayed nanostructured TiO2 films for efficient photocatalytic degradation of textile azo dye

Characterization of sprayed TiO2 on ITO substrates for solar cell applications

“…The anthocyanins belongs to the group of natural dyes, which are responsible for the several colors in the red-blue range found in fruits, flowers and leaves of the plants [7]. Various methods have been reported for the preparation of TiO 2 thin films: spin coating method [8], spray technique [9][10][11], pulse laser deposition [12], sol-gel method [13], hydrothermal method [14], chemical bath deposition method [15], RF magnetron sputtering [16], etc. In the present study highly oriented TiO 2 films with anatase phase are obtained at 450°C using Titnylacetylacetonate as precursor, whereas films with amorphous nature/less intense peaks are obtained using Ti precursor.…”

Simultaneous electricity production and Direct Red 80 degradation using a dual chamber microbial fuel cell

“…There was also a decrease in absorbance around 298 nm and an increase around 254 nm in ultraviolet region. The peak in visible region corresponds to azo bond, whereas peaks in ultraviolet region correspond to naphthalene and benzene structures [36]. These changes occurred in UV and visible region interpreted that the molecular structure of sulfonated dye Direct Red 80 changed after decolorization.…”

Photodegradation of Methylene Blue by TiO2-Fe3O4-Bentonite Magnetic Nanocomposite

“…Under illumination, the crystal surface of TiO 2 generates electrons (e − ) and holes (h + ), allowing the production of reactive oxygen species (ROS) such as hydroxyl free radicals or oxygen free radicals [7,8]. Such species react with the nitrogen double bonds in azo dyes, and the dyes are thereby decomposed into nontoxic small-molecule chemicals [9]. However, pure TiO 2 is of limited use because of its low specific surface area and low adsorption rate [10][11][12][13].…”
