英文摘要	The photocurrent conversion processes of nanoporous TiO2/conducting polymer film electrode were studied in the electrolytes with or without redox couple by using the photocurrent action spectra, the potential dependence of photocurrent and UV - vis absorption spectra. It is concluded that nanoporous TiO2/conducting polymer film electrode has a duplex n - type semiconductor layer structure. The bandgap of nanoporous film and the bandgap of poly pyrrole (PPy) film, and poly aniline (PAn) film is 3. 26, 2. 23 and 2. 88 eV, respectively, Therefore, the semiconductor electrode modified by PPy or PAn can enlarge the visible optical absorption region and obviously increase the photocurrent in visible region. The photocurrent threshold shifts to > 600 nm. This effect may improve the photoelectron conversion efficiency of the semiconductor electrodes of large bandgap.
