“…It has been reported that the heat treatment of titania particles increase the particle sizes as well as transformation from anatase to rutile phase but if some dopant (aluminum, tin or iron) are used during the synthesis then the grains sizes during heat treatment do not grow substantially as compared to the undoped sample [26]. Besides powder synthesis, sol-gel process may be used to coat other materials with layers of NTPs as Barmala et al reported the deposition of thin film and small buds of titania on the surface of MWCNTs when they are added into the hydrolyzed solution of Tetraethyl orthotitanate (TEOT) and isopropanol [28]. The coating formation on multi walled carbon nanotubes (MWCNTs) increase the surface area of NTPs enormously thus enhancing the photocatalytic efficiency of the NTPs-MWCNTs composite [28].…”

This paper reviews the synthesis methods of nano titania particles and their utilization in various applications with concise discussion on the related health concerns. Owing to the efficient photocatalytic properties of nano titania particles along with high stability, super hydrophilicity and low cost, these particles are perfect candidate for the production for coatings on the surfaces of construction materials i.e. tiles, facades, wall etc. The nano titania coatings are capable of decomposing dust, dirt and organic pollutants in the presence of sunlight. These decomposed products may then easily be washed away by rinsing thus providing easy cleaning and keeps the buildings in younger or fresh look for decades.

“…The composites are made using sol-gel method and ratios that were optimized in our previous research [20]. Tetraethyl orthotitanate (95%, Merck) was dissolved in isopropanol (obtained from Chemical Industry Co. of Dr. Mojalali IR) with molar ratio of 1 : 70.…”

This study investigates optimization of benzothiophene (BT) and dibenzothiophene (DBT) removal via a photocatalytic process by using central composite design (CCD) method. Temperature, pH, and p-25 to MWCNT ratio (g/g) in the composite structure are considered as design factors. According to the results, temperature has the greatest impact on removal rate. In optimal condition, after being exposed to UV lamps (9 W) for 20 min, 59.8% of the solutions' BT was removed, while DBT was completely removed. Although the generated structure band gap is 3.4, but due to the presence of MWCNTs in the structure, it is capable of absorbing visible light, and this leads to complete removal of DBT and 42% removal of BT under visible light radiation (in similar circumstances). Kinetics analysis of thiophene's reaction showed that, in the presence of visible light, first order removal rate constants for DBT and BT are 7.98 and 0.953 1/h, respectively.
