Titanium electrodes coated by TiO2 (anatas) were prepared by decomposition of peroxotitanic compounds. Their photoelectric behavior in 1 M LiClO4/PC (propylene carbonate) was investigated. The photoeffect was emphasized by the process of electrolytic incorporation and removal of lithium. The effective threshold energy was 1.5 to 1.6 eV, thus indicating donor dissociation being the basic photochemical process.
