In a similar way, a well-adhered surface modification of BC fibers can be achieved with Ti(>2 nanoparticles (with a diameter of about 10 nm) by the hydrolysis of titanium tetraisopropanolate adsorbed onto the fibers. It was observed that the titania-coated surface appears to be dense and have low porosity and to consist of near-spherical grains. By washing with sodium carbonate solution, the TiC>2 films were not removed during neutralization. It seems that the particles have formed strong interactions with BC. The coated membranes showed substantial bactericidal properties under UV radiation and white light (containing a small fraction of UV) conditions, too. This effect is caused by the photocatalytic destruction of the bacterial cells.

Only a few recent studies have dealt with the use of photoactive membranes prepared by immobilization of titania particles in polymeric membranes or deposition of porous titania coatings. " They were concerned with photooxidation applications like antifouhng or elimination of small organic molecules that cannot be stopped by conventional membrane treatments, but which are very harmful to the environment, like VOCs.

An example of a photochemical cyclization was reported by Takei et al. [92], who demonstrated the synthesis of L-pipecolinic acid (160) from an aqueous solution of L-lysine (161), as illustrated in Scheme 6.42. To achieve this photocatalytic transformation, the authors fabricated a Pyrex micro reactor in which the channel cover plate was coated with a 300nm layer of anatase Ti02 (100 nm particles), to afford a titania-coated micro reactor (TCM) the titania film was subsequently loaded with platinum (0.2 wt%), by photodeposition, to enable the TCM to be used...

Apparatus. For preparation of ROS-containing water, photocatalytic apparatus designated exPCAW-1 (fabricated by K2R Inc., Kitakyushu, Japan) was used. It comprised an ultraviolet (UV-A) emitting bulb, ultrasonic wave (USW) generating devices, sheets of titania-coated fiber, a pumping system and gas (02 or NO) supply systems. As circulated in the exPCAW-1, water is treated with UV, USW and 02, enabling the photo-catalytic oxidative conditioning of the water.

A related study showed the important influence aging of the sol has on the topographical structure of sol-gel deposited titania coatings developed as precursors for subsequent calcium phosphate deposition from SBFs (Peltola et al., 2000). In their study, different sol-gel-derived titania coatings were produced on titanium...
