Study on the photocatalytic activities of TiO2 films prepared by reactive RF sputtering

Anticorrosion assessment of Al2O3‐TiO2 composite thin films derived from sol‐gel dipping technique

“…The significant point was related to sample 1. In spite of the fact that the transformation of anatase to rutile phase starts from 600°C, with increasing of temperature up to 800°C, the anatase phase was still stable and a low amount of rutile was formed. Increasing the Al‐precursor caused anatase to be intensely stabilized up to this temperature.…”

Exploring a new phenomenon in the bactericidal response of TiO2 thin films by Fe doping: Exerting the antimicrobial activity even after stoppage of illumination

“…Determination of crystalline phases and chemical states for the Fe-TiO 2 coated samples. In general, TiO 2 induces a structural transformation from anatase at low temperature (50 °C) to rutile at high temperature (600 °C) [23]. A new phase called Ankerite appears due to Fe-doping.…”

Application of Taguchi Method for Characterization of Corrosion Behavior of TiO2 Coating Prepared by Sol‐Gel Dipping Technique

“…Moreover, the quality control of anatase phase was easier in comparison with that of rutile phase . In general, the crystallization of TiO 2 films followed as: anatase → anatase + rutile → rutile, when calcination temperature was increased from 50 to 600°C . To obtain anatase phase, different calcination conditions (450°C; 0.5 h, 550°C; 1 h and 500°C; 1 h, 400–900°C; 1 h) were reported in several studies.…”

“…rutile, when calcination temperature was increased from 50 to 600°C. 19 To obtain anatase phase, different calcination conditions (450°C; 0.5 h, 2 550°C; 1 h 9 and 500°C; 1 h, 11 400-900°C; 1 h 20 ) were reported in several studies. In another attempt, 2 to improve crystallinity of anatase phase, PEG was used as an additive to increase calcination temperature to 500°C for 4 h without formation of any rutile phase.…”
