“…Photocatalysis as a useful tool for the self-cleaning of glass, polymer thin films and textile fabric surfaces has recently been reported by Daoud [1][2][3][4], Kiwi [5][6][7][8], Hashimoto/Fujishima et al [9,10], Bahnemann [11][12][13], Radetic [14] and Pakkanen [15]. TiO 2 has been chosen as the standard photocatalyst used in the field of environmental photochemistry due to its stability, effective separation of charges under band-gap irradiation and availability of fairly pure samples.…”

“…There is nowadays a need to develop resistant photocatalysts presenting faster self-cleaning kinetics compared to TiO 2 and composite-TiO 2 surfaces which are too slow for many industrial applications [5][6][7][8][11][12][13]. The second area that needs improvement lies in the fact that most of the self-cleaning films are deposited from colloids on surfaces that are subsequently heated to diffuse and anneal the colloid into the surface at temperatures that fabrics and polymer films do not resist [5][6][7][8][9][10][11][12][13].…”

a b s t r a c tUniform adhesive TiO 2 -ZrO 2 films co-sputtered on polyester (PES) under low intensity sunlight irradiation discolored methylene blue (MB) within 120 min. The discoloration kinetics was seen to be accelerated by a factor four by TiO 2 -ZrO 2 -Cu containing ∼0.01% Cu, as determined by X-ray fluorescence (XRF). TiO 2 -ZrO 2 -Cu also increased also accelerated by a factor the discoloration of MB compared to TiO 2 /Cu(PES). MB discoloration was also monitored under visible light in the solar cavity by using a 400 nm cutoff filter. Photocatalyst surfaces were characterized by spectroscopic methods showing the film optical absorption and by X-ray photoelectron spectroscopy (XPS), the surface atomic percentage concentration up to 120 nm (∼600 layers). The band-gaps of TiO 2 -ZrO 2 and TiO 2 -ZrO 2 -Cu were estimated for films co-sputtered for different times. By Fourier transform attenuated infrared spectroscopy (ATR-FTIR), the systematic shift of the predominating s (CH 2 ) vibration-rotational MB bands was monitored up to complete MB discoloration under low intensity solar simulated light. Evidence is presented for the OH • generation by TiO 2 -ZrO 2 -Cu participating in the self-cleaning mechanism. The photo-induced interfacial charge transfer (IFCT) on the TiO 2 -ZrO 2 -Cu is discussed in terms of the electronic band positions of the binary oxides and Cu intra-gap states. This study presents the first evidence for a Cu-promoted composed of two binary oxide semiconductors accelerating the self-cleaning performance.

“…Titanium dioxide, particularly due to the dynamic development of nanotechnology, is now used in many processes of photocatalytic decomposition of organic substances (Fujishima et al 2008;Ochiai et al 2010Ochiai et al , 2014. It is applied, inter alia, onto textile materials in order to induce self-cleaning properties (Zhang et al 2012;Cieślak et al 2015;Bozzi et al 2005;Dastjerdi and Mojtahedi 2013;Tung and Daoud 2011;Radetic 2013;Cieślak et al 2009;Bourgeois et al 2012). In our study, the photocatalytic effectiveness of the fibers was evaluated on the basis of sorption and the nicotine decomposition rate under different conditions.…”

Textile materials, because of their specific character, can affect the content of volatile pollutants in the indoor air, including the constituents of tobacco smoke (ETS-environmental tobacco smoke). Polypropylene fibers have a particularly high susceptibility for the sorption of nicotine. Textiles made of polypropylene are often used in different rooms or offices. The aim of the research was to give polypropylene fibers the photocatalytic properties by modifying their surface, using titanium dioxide doped with nanoparticles of silver (TiO 2 /Ag). Modification of polypropylene fibers with TiO 2 /Ag increases their susceptibility to sorption of nicotine and accelerates its decomposition. A comparison of the decomposition rate constants for the modified and unmodified fibers shows that the decomposition process runs from 1.6 to 2.9 times faster for the modified fibers depending on the nature of modification, the source of the nicotine and the ambient conditions. It was also found that the strength of modified fibers does not change under irradiation.

By coating fibers with titania sol to generate a dual-size surface roughness, followed by hydrophobization with stearic acid, 1H, 1H, 2H, 2H -perfluorodecyltrichlorosilane or their combination, hydrophilic cotton fabrics were made superhydrophobic. The surface wettability and topology of cotton fabrics were studied by contact angle measurement and scanning electron microscopy. The UV-shielding property of the treated fabrics was also characterized by UV-vis spectrophotometry.
