“…These compounds were detected after reaching the adsorption saturation. Based on the amount of the produced phosgene, almost all of the provided TCE was finally transformed into phosgene during the photocatalytic degradation of TCE using Sample T. This is because a greater amount of the adsorption species, such as DCAC, was transformed into phosgene in the latter run by the UV activation of TiO 2 [29,33]. Most of the produced phosgene was emitted from the Sample T surface into the gas phase.…”

A highly adsorptive allophane−TiO 2 nanocomposite photocatalyst was prepared by dispersing nanoparticles of the natural clay mineral allophane into a titanium alkoxide solution by the sol-gel method. During the photocatalytic degradation of trichloroethylene using the allophane−TiO 2 nanocomposite, emission of the intermediate product, phosgene, was drastically inhibited.Trichloroethylene was transformed into the intermediate products,phosgene and dichloroacetyl chloride, on the TiO 2 during the UV irradiation. These compounds are rapidly adsorbed on the allophane. The compounds then gradually degraded after diffusing to the TiO 2 .

“…Photocatalytic reactions have attracted much interest with regard to decomposition and mineralization of pollutants and undesirable compounds in air and waste water [1][2][3][4][5][6][7][8][9][10]. The reactions are also interesting from the viewpoint of organic syntheses [11][12][13][14][15][16][17].…”

Photooxidation of organic compounds in a solution containing hydrogen peroxide and TiO2 particles under visible light

et al. 2005

Cyclohexane was oxidized under visible light in a titanium dioxide suspension containing hydrogen peroxide. Cyclohexanol and cyclohexanone were detected as products. Under similar experimental conditions, nonyl aldehyde was oxidized to nonylic acid. The reaction rate for the oxidation on rutile particles was faster than that on anatase particles. When hydrogen peroxide was added to suspensions of these particles, both rutile and anatase particles became yellow-colored due to the formation of peroxide complexes on their surfaces. The difference between the reaction rates for rutile and anatase particles suggests that the properties of the peroxide complexes formed on these particles are different. The properties of these complexes were studied by UV-vis spectroscopy.

“…For instance, a study led on chlorophenol showed that, depending on the wave length of the incident light, the molecule could react by OH addition without Cl -removal to form chlorocatechol or with Cl -removal to form hydroquinone [193]. In the halogenated acids family, the carboxylate group interacts with TiO 2 and a Kolbe reaction is first observed in most of the cases [194].…”

Nanomaterials: A Danger or a Promise?

TiO 2 -based heterogeneous photocatalysis is a process that develops rapidly in environmental engineering and it is now employed in several industrial domains, including water treatment, air purification, and self-cleaning surfaces. Photocatalysis is a natural phenomenon in which the TiO 2 accelerates a chemical reaction through the action of light, without being altered. The illuminated TiO 2 induces the formation of reactive species, able to decompose by oxidation and/or reduction reactions organic or inorganic substances. The major part of the applications of photocatalysis corresponds to organic oxidation, and it is now considered as one of the Advanced Oxidation Technologies (AOTs), gathering the reactions mainly based on hydroxyl radical (HO • ) chemistry. The development of a system based on photocatalysis requires gathering knowledge of numerous and various scientific domains: physical-chemistry, materials science, catalysis, environmental chemistry, biology, and engineering science. This chapter is therefore designed to give a detailed survey of the different scientific fields concerning TiO
