Characterization of self-cleaning glasses using Langmuir–Blodgett technique to control thickness of stearic acid multilayers

Long term self-cleaning and photocatalytic performance of anatase added mortars exposed to the urban environment

“…5. This was ascribed to the mineralization of organic compounds formerly adsorbed on the surface, which causes surface yellowing due to reaction products remaining on the surface [63], which underlines the fact that TiO 2 containing mortars, in addition to the self-cleaning features, also contribute to the degradation of polluting compounds in the atmosphere.…”

Photocatalytic antibacterial activity of nano-TiO2 (anatase)-based thin films: Effects on Escherichia coli cells and fatty acids

“…It was not possible to measure the effects of UV-A radiation on nonphotocatalytic surface due to technical reasons (the fatty acids evaporated from smooth Si (100) surface during pumping before XPS spectra could be measured). However, it has been shown that photochemical effects potentially occurring on Si-monocrystal surface are at least 10 times smaller than photocatalytic effects that take place on TiO 2 surface and can be therefore neglected [49].…”

Photocatalytic construction and building materials: From fundamentals to applications

“…Small particles and greasy deposits are adhered to building surface by organic binders such as hydrocarbons and fatty acids [30]. Taking fatty acid molecules for example, their carboxylic groups (-COOH) enable them to stick on building surface via chemical binding with calcium ions present in concrete; on the other hand, their long chains link with other hydrophobic molecules perpendicularly to the surface, resulting in fatty stains which trap many atmospheric particles and dusts.…”
