“…In a standard synthesis, 0.2 g of titanium nanoparticales (P25) in aqueous solution of NaOH (10M, 40ml) was placed into a Teflon-lined autoclave. [26] The mixture of titanium dioxide nanoparticales and strong alkaline aqueous medium of NaOH was stirred to form a suspension solution (which is milky in appearance), sealed and hydrothermally treated at 220-260 C for more than two days. The precipitate formed was separated by filtration and washed with de-ionized water until a pH value near 8 was reached.…”

Summary Heavy metal contamination in drinking water has become an ecotoxicological hazard of prime interest. Conventional treatment technologies, such as chemical precipitation, coagulation and ion‐exchange, are often restricted because of some technical or economic constraints. In view of this, the search for a more innovative and effective adsorbent for the removal of toxic metal ions has intensified in recent years. In this study a novel adsorbent, titanium dioxide nanowire (TiO2), is prepared by using hydrothermal methods and subsequently used for heavy metal removal. This study tests the potential of using the TiO2 nanowire to remove heavy metal (Pb2+, Cu2+, Fe3+, Cd2+ and Zn2+) residues from contaminated water. TiO2 nanowire is an exceptional adsorbent material due to its magnetic properties and a good adsorption capacity. The highest absorption efficiency was 97.06% obtained with Pb2+ and the lowest was obtained with Zn2+ at 35.18%. The application of these materials in water filters may be a promising and economically feasible technology for water purification.

“…(Singh et al, 2007). Numerous examples of polymer-TiO 2 nanocomposites have been described in the literature, such as polystyrene/TiO 2 (Youssef, Kamel, & El-Samahy, 2013), TiO 2 -poly (styrene-divinylbenzene)/maleic anhydride (Li et al, 2010), polypyrrole/TiO 2 (Yuvaraj, Park, Gal, & Lim, 2008), PMMA/TiO 2 (Haroun & Youssef, 2011), and polyaniline/TiO 2 (Youssef, 2014).…”

“…In particular, nanoparticle-polymer composites were obtained by grafting end-functionalized polymers to NPs 32 or by grafting polymers from NPs with in situ monomer polymerization. 29,33 Several examples of TiO 2 -polymer composites have been described in the literature, such as TiO 2 -poly(styrene-divinylbenzene)/maleic anhydride, 34 TiO 2 -polypirrole, 35 TiO 2 -PMMA, 36 TiO 2 /poly (amide-imide), 37,38 TiO 2 /P(St-co-DVB)-MAA, 39 TiO 2 /polystyrene, 40 TiO 2 (SiO 2 )/PVDF/PMMA, 41 TiO 2 / (VAc-BuA), 42 TiO 2 /PET. 43 In this work, NCs (NPs-Oligoamide), containing hydroxylated oligomers derived from renewable sources and covalently bonded to anatase TiO 2 nanoparticles, were synthesized with the purpose of obtaining new formulations with antimicrobial properties to be used afterward on wooden surfaces.…”

Homogeneous core-shell systems were obtained with a growth, in controlled steps, of several oligoamides on TiO 2 nanoparticles. Derivatives of natural compounds, such as L-tartaric acid and a,a 0 -trehalose, were used as diesters in the polycondensation reactions with ethylenediamine. TiO 2 anatase was chosen because of its high photo-activity and its antimicrobial activity. The TiO 2 nanoparticles had been previously activated then functionalized using two different coupling agents, and finally, the TiO 2 -oligoamide nanocomposites were synthesized using two synthetic pathways. The final products were characterized by 1 H NMR, 13C NMR, FT-IR, and transmission electron microscope. These nanocomposites can show improved properties in comparison with the single components (TiO 2 nanoparticles or oligoamides), which are useful in many fields, such as antimicrobial coatings for surfaces in cultural heritage conservation. A nanocomposite (TiO 2 -polyethylenetartaramide) was used for applicative studies, and it has shown a good efficacy against fungal attack by Trametes versicolor on wood specimens (Fagus sylvatica).
