Sol–gel-derived super-hydrophilic nickel doped TiO2 film as active photo-catalyst

Dielectric properties of Fe-doped TiO2nanoparticles synthesised by sol–gel route

“…Titanium sol was prepared with titanium butoxide, as reported elsewhere [15] in acidic medium using isopropyl alcohol (IPA) as solvent. The mixture was stirred vigorously using magnetic stirrer with Teflon (polytetrafluoroethylene) coated bit.…”

A comparative study about the effects of isomorphous substitution of transition metals (Ti, Cr, Mn, Co and Ni) on the UV/Fenton catalytic activity of magnetite

“…From previous researches [30,33], some substituting cations created the oxygen vacancies [28,29], which were shallow traps to inhibit the recombination of photo-generated electrons and holes (Eq. (10)), and thus prolonged the lifetime of charge carriers [34,35].…”

“…For substituted magnetite samples, both the broadening of diffraction lines at ca. [28][29][30][31][32][33][34][35][36][37][38][39] • and the shift of peaks at ca. 35.5 • toward lower diffraction angle indicate the incorporation of substituting metals into inverse spinel structure, which is resulted from the difference in ionic radii between iron and substituting metal cations (Table 1) [21].…”

Sol–gel derived nickel-doped TiO2films as wear protection coatings

“…Nickel-doped TiO 2 has shown several interesting properties like photo-catalytic activity and UV light-induced hydrophilicity [14][15][16][17][18]. However, information regarding the mechanical and tribological performance of Ni-doped TiO 2 is not available, though this is a crucial problem faced during the engineering application of films.…”
