“…For examples, TiO 2 nanowires on graphene oxide and pine tree‐like TiO 2 nanotubes on a transparent conducting oxide substrate were synthesized by a one‐step hydrothermal method . Using a combined method of electrospinning, hydrothermal processing, and calcination, Song et al synthesized branched open‐ended TiO 2 nanotubes . By etching surface‐fluorinated and amorphous TiO 2 solid spheres in fluoride, urchin‐like mesoporous TiO 2 hollow spheres were synthesized .…”

Anatase titania (TiO 2 ) nanoparticles were synthesized via a self-developed ethanol vapor-thermal method at 240°C (T240) and 250°C (T250), i.e. at temperatures lower and higher, respectively, than the supercritical temperature (243.5°C, 7.0 MPa) of ethanol. Compared to T240, T250 exhibited a higher ratio of exposed (001) facets, oxygen vacancies, and concomitant TiO x . The specific surface area of T250 was 119.0 m 2 g −1 , smaller than that of T240 (144.2 m 2 g −1 ). During the degradation of methylene blue, T250 exhibited a high apparent rate constant (K app ) of 14.5 × 10 −2 min −1 , which was 6.3 times larger than that for T240. Furthermore, compared to T240, T250 exhibited better performance toward degradation of phenol. Results of electron spin resonance spectroscopy and photoluminescence indicated that the photogenerated electron-hole pairs possessed higher separation efficiency for T250 than for T240. In summary, the excellent photocatalytic performance of T250 originates from the higher ratios of exposed (001) facets, oxygen vacancies or TiO x , C═O groups adsorbed at the surface of particles, and higher separation efficiency of photogenerated electron-hole pairs. By employing this selfdeveloped vapor-thermal method, a variety of catalysts and their composites can be synthesized, which may exhibit novel morphological characteristics and properties as well as excellent photocatalytic performance.

“…7,8 Usually TiO2 paste is deposited on a TCO glass substrate and subjected to annealing above 500 °C in order to facilitate inter particle necking and removal of binders present in the paste. 9 On comparison with rigid substrates, panels made from flexible substrates have an advantage during the installation process of panels over the roofs with flat or curved surfaces because of light weight, 10 and roll-to-roll method. 11 These flexible polymer substrates could be moulded into different shapes and portable panels as power sources for electronic devices such as mobile phones, cameras and etc.…”

Binder free TiO2 paste is prepared using tert-butyl alcohol in dilute acidic conditions at room temperature for flexible polymer dye sensitized solar cells (DSSC). The present paper reports the detailed studies carried out to elucidate the importance of stirring times during the paste preparation on the final device performance. The maximum conversion efficiency of 4.2 % was obtained for flexible DSSCs fabricated on ITO/PEN substrates using TiO2 paste prepared from an optimum stirring time of 8 hours. The effect of optimum stirring times on the device characteristics has been understood in terms of the detailed morphology and surface area measurements.
