The nanoporous TiO₂ film electrodes have been prepared by a sol-gel deposition process.The photostability of the electrodes in basic solutions has been studied. The results show that the photostability of the electrodes decreases rapidly in strong basic solutions with or without methanol. The reaction of holes to O_ad^2- produces active O_ad^- atoms and the products O_ad^- atoms oxidize Ti³⁺ to Ti⁴⁺ on TiO₂ film surface and subsurface. This results in the TiO₂ film electrodes unstable in basic solutions both without methanol and with too low concentration.
