Transparent, photocatalytic, titania thin films formed at low temperature

Synthesis and Applications of Nano Titania Particles: A Review

“…The produced gel may be cast into solid shapes, thin films or coatings and their further heat treatment transforms the gel into a dense and hard material [11][12][13][14][15][16][17][18][19][20]. The sol-gel method is so versatile that by controlling the reaction parameters various products ranging from aerogels to ceramic fibers and solid castables to ultrafine powders may be produced [16,17,[21][22][23][24]. Titania nano particles have been synthesized using various precursors, solvents, catalysts, peptizing and complexing agents under different temperature and aging conditions [17,25,26].…”

Polarization-Dependent Raman Spectroscopy of Epitaxial TiO2(B) Thin Films

“…Titanium dioxide (TiO 2 ) exhibits a number of structurally distinct phases, the best known of which are rutile, brookite, and anatase. The bronze phase of titanium dioxide, TiO 2 (B), a monoclinic polymorph first described in 1980, has recently attracted much interest due to its unusual layered structure and potential applications in Li-ion batteries, − photocatalysts, − chemical sensing, − and dye-sensitized solar cells. − There are many reports in the literature on its synthesis as nanopowders and nanostructures by hydrothermal methods, ,, aqueous solutions, , and calcination of amorphous films . In all of these cases the material produced has been impure and often poorly crystalline, containing a considerable fraction of anatase as well as water from synthesis, which is thought to play a role in stabilizing the TiO 2 (B) phase. , A few recent reports of TiO 2 (B) films produced by chemical hydrolysis and by electrophoresis of nanopowders have yielded micron-thick nanostructured films, but these are of poorly crystalline quality.…”

Hydrothermal synthesis of mixed phase blue titanium dioxide from oxalate stabilised sols

“…Over the past 40 years the use of anatase as a photocatalyst has attracted immense attention [1]. It can be used in the degradation of waste, used to produce self-cleaning materials and photocatalytic water splitting [1][2][3]. Many studies have been carried out to maximise its photocatalytic activity by modifying crystal phase [4], morphology [5] and crystal size [1].…”
