In this study, we reveal new insights of the key factors controlling the photocatalytic and photoelectrochemical properties of CNT/TiO2 composites prepared by the surfactant wrapping sol-gel technique [1-2]. Particularly, we suggest that the key parameters that govern the composite behavior differ depending on whether the composite is used in a suspended photocatalytic system (a slurry suspension) or it is immobilized on a conductive support in a photo-electrochemical system (a photoanode). We show that the thickness of the TiO2 layer and the conductivity of the composite (which increases with the CNT content) have profound effects on the photocatalytic and photoelectrocatalytic properties of the composites in each of the above applications [3].
