Abstract: Photoactive TiO₂ surface layers were prepared by the sol-gel process. Their photoelectric activities were judged from measured effective quantum yields of photocurrent. It was found that the photoelectrochemical deposition of o-toluidine, pyrrole, and aniline takes place on these surface layers. Changes of hydrophilic-hydrophobic surface nature accompanied with the photoelectrochemical deposition of organic layers were evaluated by measuring contact angle of water drop.
