Abstract
The current‐potential characteristics of n‐TiO2 electrodes have been investigated in a photoelectrochemical cell. Photoresponse induced by the light of energy lower than the band gap of TiO2 has been observed in the potential range between −1.0 and −1.4 V vs SCE in 1N NaOH. The photoresponse, which is sensitive to the oxygen gas dissolved in solution, has been attributed to some surface states at the TiO2‐electrolyte interface.Keywords
