Anomalous photoresponse of n‐TiO2 in a photoelectrochemical cell was previously observed to be induced by light of energy lower than the bandgap. This photoresponse was attributed to surface states at the TiO2‐electrolyte interface. We studied this effect at stationary and rotating disk TiO2electrodes and we show that the anomalous photoresponse is a thermal effect due to heating of the crystal surface by the illumination.

Abstract
Anomalous photoresponse of n‐TiO2 in a photoelectrochemical cell was previously observed to be induced by light of energy lower than the bandgap. This photoresponse was attributed to surface states at the TiO2‐electrolyte interface. We studied this effect at stationary and rotating disk TiO2electrodes and we show that the anomalous photoresponse is a thermal effect due to heating of the crystal surface by the illumination.File allegati a questo prodotto
