“…Few researchers synthesized TiO 2 for photo catalytic applications [17][18][19][20][21][22][23][24]. However, the result of the present work depicts higher degradation when compared to these reports [17][18][19][20][21][22][23][24].…”

In the present study, TiO 2 quantum dots (QDs) were effectively synthesized by the solgel method and it was characterized by several techniques. The structure of the TiO 2 QDs, before and after calcination, was analyzed by the powder X-ray diffraction technique. The XRD results indicate that after calcination, TiO 2 QDs have pure anatase phase with tetragonal structure without any other phases and impurities. The morphology and size of the TiO 2 QDs were determined from FE-SEM and TEM analysis. The optical band gap of TiO 2 QDs was estimated using KubelkaMunk function from diffuse reflectance spectroscopy. The photocatalytic activity and recycling ability of the TiO 2 QDs have been investigated. The TiO 2 QDs were used to degrade the model dyes such as methyl orange and methylene blue under UV light irradiation and their results have been discussed. A mechanism is proposed and discussed accordingly in detail. ª 2015 The Authors. Production and hosting by Elsevier B.V. on behalf of King Saud University.

“…The morphological structure of anodized TiO 2 nanotubes as well as their photocatalytic activity can be modified by changing preparation conditions, like anodization time, applied voltage, temperature, Ti foil roughness, calcination parameters and electrolyte composition including fluoride concentration, solvent, water content, pH, viscosity, conductivity, and organic additives [15,16]. According to Zhang et al [17] there are several generations of TiO 2 nanotubes produced via anodic oxidation.…”

Abstract:Sol-gel modified TiO 2 powder composite films were prepared as photoeletrode for the hydrogen generation in a two-compartment photoelectrochemical cell. Commercial Degussa P25 TiO 2 powders have been successfully incorporated into TiO 2 sol prepared by sol-gel method using tetrabutyl orthotitanate as precursor material to form thick TiO 2 films via coating on the indium-tin oxide (ITO) conductive glass. With assistance of polyethylene glycol (PEG), the macroporous structure TiO 2 film was obtained after calcination. The film samples were characterized by XRD, SEM and UV-Vis spectrophotometer. The XRD result indicated that TiO 2 films were composed of the anatase-rutile mischcrystal phase. Furthermore, the coating layer had a great effect on the photoelectrochemical properties and photocatalytic activity. The experimental results showed that TiO 2 -P25/ITO film with 5 coating layers demonstrated a maximum hydrogen production rate, which implied that TiO 2 -P25/ITO film prepared by this convenient and economic method is a promising photocatalyst for efficient hydrogen production.
