TiO 2 thin films doped with neodymium(Nd) in the range from 0 at.% to 10at. % were prepared on glass substrates by sol-gel dip-coating method. Water contact angle on the Nd-doped TiO 2 films were measured by contact angle analyzer. The water contact angle measurement result showed that the hydrophily of the films improved when the Nd 3+ concentration increased to 5 at.%. The photocatalytic activity of the undoped and Nd-doped TiO 2 thin films were investigated by the degradation of methylene blue under high-voltage mercury lamp. The results showed that 5 at.% Nd-doped TiO 2 thin film exhibited the highest photocatalytic efficiency.

“…The temperature of 400 o C which gave the smallest crystallite size yielded the most active coating as reported in [21]. The shortest photo-bleaching time gives an RZ ink reduction rate (≈ 0.0125 s -1 ), which is much higher than the highest reduction rate reported by Zita et al [39] for TiO 2 coatings deposited on glass substrate with a SiO 2 precoating by sol-gel method. The photo-bleaching times for the 12.6 µm thick coatings deposited at 400 o C have been compared to those of commercial self-cleaning glass.…”

A scaled-up pulsed-pressure MOCVD system was used to deposit TiO 2 coatings from tetra-isopropoxide precursor solution on stainless steel substrates and on 3-D objects. The objective of the work is the production of antimicrobial coatings for handles in health care facilities. Antimicrobial coatings are sought to manage the transmission of hospital acquired infections (HAI's), which are reported to cost around one million pounds per annum in the UK alone. Titania is a promising material for this application due to the photocatalytic production of reactive oxygen species that are crucial for the destruction of organic pathogens.TiO 2 coatings of 0.2 to 13 µm thickness were deposited at temperatures between 375 o C and 475 o C. The crystallite size and photocatalytic activity are influenced by deposition temperature. No dependence of stoichiometry on the deposition temperature has been observed. The films on stainless steel exhibit reasonably good photocatalytic performance. The photocatalytic performance and the stoichiometry improve with the film thickness. A three dimensional object (door handle) was coated with good conformity. The reactor scale-up for coating production on door handles is proposed for future wear and hygiene performance testing.
