The preparation and characterization of photocatalytically active TiO2 thin films and nanoparticles using Successive-Ionic-Layer-Adsorption-and-Reaction

Recent status of chemical bath deposited metal chalcogenide and metal oxide thin films

“…Homogeneous and close packed TiO 2 films without preferred orientation were deposited on silicon wafers by Park et al [296]. Particle sizes from ten to a couple of hundred nanometers were obtained after hydrothermal annealing and/or firing in a furnace after the initial deposition.…”

Synthesis of photosensitive nanograined TiO2 thin films by SILAR method

“…In recent years, many studies related to the synthesis of anatase TiO 2 have been focused on the control of morphology as well as particle size. Many deposition methods such as thermal and anodic oxidation of titanium [11], electron beam evaporation [12], chemical vapor deposition [13], sol-gel [14], spray pyrolysis [15], chemical bath deposition (CBD) [16][17][18], successive ionic layer adsorption and reaction (SILAR) [19][20][21], electrodeposition [4,22], etc. have been reported to prepare nanocrystalline TiO 2 thin films.…”

TiO2 hydrosols with high activity for photocatalytic degradation of formaldehyde in a gaseous phase

“…However, one of the difficulties in application of TiO 2 for indoor air purification is how to coat the catalysts such as P-25 powder onto walls, windows, or furniture easily and durably, without any significant blights such as changes in color and transparency of materials after coating. The precursor sols for conventional TiO 2 thin films should be first coated on the substrate, and then sintered at 400-500 • C to acquire higher crystalline because a good anatase structure is to need a higher sintering temperature more than 400 • C for a sol-gel process [16][17][18]. TiO 2 hydrosol would be a more suitable catalyst since it is easy to coat and form a stable TiO 2 thin film on the substrates at room temperature and harmless to the materials.…”
