| 英文摘要 | The photocurrent conversion processes of nanoporous TiO2/poly pyrrole (PPy) 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/PPy film electrode has a duplex n-type semiconductor layer structure, The bandgap of nanoporous film is 3.26 eV, and the bandgap of PPy film is 2.2 eV. Therefore, the semiconductor electrode modified by PPy can enlarge the visible optical absorption region and increases obviously the photocurrent in visible region, The photocurrent threshold shifts to >600 nm and this effect can improve the photon-electron conversion efficiency of the semiconductor electrodes of large bandgap. |
