Abstract:
A thin layer of TiO 2 with photocatalytic property was employed as an interlayer to facilitate electron transfer in a conventional photoanode consisting of Fe 2 O 3 and fluorine-doped tin oxide (FTO) films. The photoelectrochemical performance was compared between the samples with and without the TiO 2 interlayer. The photoanode with the interlayer showed a greatly improved performance under 100 mW/cm 2 UV–vis light illumination; the onset voltage for the photocurrent shifted to a 20% smaller value of about 0.75 ( V vs real hydrogen electrode) and the photocurrent density of 4.35 mA/cm 2 at 1.23 ( V vs RHE) was observed, which is 3.5 times larger than that obtained from the photoanode without the TiO 2 interlayer. The effect of the TiO 2 interlayer on the photoanode performance was systematically investigated, and an effective way to improve the photoanode was suggested.
