Antibacterial activity of thin-film photocatalysts based on metal-modified TiO2 and TiO2:In2O3 nanocomposite

A new visible light active multifunctional ternary composite based on TiO2–In2O3 nanocrystals heterojunction decorated porous graphitic carbon nitride for photocatalytic treatment of hazardous pollutant and H2 evolution

“…Since the CB and VB positions of In 2 O 3 (∼ − 0.6 eV and ∼ + 2.2 eV, respectively, vs. NHE) [37,38] are both higher than those of TiO 2 (∼ − 0.3 eV and ∼ + 2.9 eV, respectively, vs. NHE) [39], the formation of TiO 2 @In 2 O 3 heterojunction allows for the effective interfacial charge transfer. The coupling of TiO 2 with appropriate In 2 O 3 contents have been proved to possess enhanced photocatalytic activities as compared with single TiO 2 since In 2 O 3 helps increase photochemical responses of TiO 2 by altering band gap energy, expediting electron transfer, and reducing recombination of photogenerated charge carriers [40][41][42][43].…”

Titanium compounds and their impact on the transformation of air pollutants

“…Antibacterial action is based on the occurrence of free radicals under the influence of UV radiation. To increase the effectiveness of antibacterial action, it is possible to join TiO 2 with other antibacterial substances, like colloidal silver, compounds of metals or organic compounds (Cheng et al 2006, Skorb et al 2008, Gao et al 2012). Due to its septic qualities, TiO 2 application is more and more universal in the production of apparel and "breathing fabrics".…”

Semiconductors in Organic Photosynthesis

“…TiO 2 photoactivity reaction assists the intrusion of the copper ions into the cell, which is probably the cause of the destruction of the E. Coli colonies even under very weak UV light. Actually several nanostructured TiO 2 derivatives are studied and applied as germicidal species, especially on the treatment of water contaminated with pathogenic microorganisms presenting a potential hazard to animals and human beings (Mccullagh et al, 2007;Skorb et al, 2008).…”
