Crystallization behaviors of TiO2 films derived from thermal oxidation of evaporated and sputtered titanium films

Thermo-induced hydrophilicity of nano-TiO2 thin films prepared by RF magnetron sputtering

“…This reaction is Eq. (3): 2Ti 3+ 4H 2 O → 2TiO 2 + 6H + + H 2 (3) Fourth, the hydrophilicity is related to surface properties, it is well known that a rough surface also improves the hydrophilicity [18]. In our work, it can be seen that the hydrophilicity enhances with increasing roughness to a certain extent.…”

“…Since then, hydrophilic titanium dioxide materials have attracted attention for many practical applications such as self-cleaning and antifogging materials. TiO 2 thin films can be prepared by numerous techniques such as chemical vapor deposition [2], thermal oxidation of electron beam evaporation [3], ion assisted deposition [4], sol-gel processes [5,6], and sputtering [7,8]. Among these techniques, RF magnetron sputtering method provides more advantages in controlling the microstructure and composition of the films.…”

Crystallinity control on photocatalysis and photoluminescence of TiO2-based nanoparticles

“…TiO 2 is widely used in various areas because of its versatile properties [1][2][3][4][5][6][7][8][9][10][11][12]: such as catalytic activity, photocatalytic activity for pollutant removal, good stability toward adverse environment, photoelectrochemical conversion, sensitivity to humidity and gas, and nonlinear optics. Being a potential solution to the recent severe problems of energy shortages and environment crises, photocatalysis has been studied extensively since Fujishima and Honda announced a TiO 2 photochemical electrode for splitting water in 1972 [13].…”

Visible light-driven nitrogen doped TiO2 nanoarray films: Preparation and photocatalytic activity

“…Conventionally, TiO 2 coatings have been prepared by casting TiO 2 crystalline powder with organic binder and subsequently heating for removal of the organics [10][11][12]. Chemical vapor deposition (CVD) [13], magnetron sputtering [14], sol-gel method [15,16], ion beam assisted evaporation [17], thermal oxidation [18], successive ionic layer adsorption and reaction [19], and hydrothermal method [20] are also applicable for the production of homogeneous thin films.…”
