Acid-doped polyaniline (PAn) as sensitizer for TiO2 nanoporous film was inv
estigated using electrochemical and photoelectrochemical methods. The photo
current generation of TiO2 nanoporous film sensitized by PAn extends into v
isible and infrared regions, and a maximum value appears in the region of 6
00-700 nm. The mechanisms of sensitization have been discussed in this pape
