英文摘要	A new photoanode polypyrrole nanowire/TiO₂ nanotube (PPy NW/TiO₂ NT) nanocomposite material with a coaxial heterojunction structure is constructed by electrodeposting p-type polypyrrole nanowire into n-type TiO₂ nanotubes. Photo-induced open circuit potential, photocurrent density, electrochemical impedance spectroscopy, and Tafel curves are measured under visible light to evaluate the photocathodic protection effect and anticorrosion properties of the nanocomposite. The results indicate that the synergistic effect between the photogenerated cathodic protection and the favorable corrosion resistance of the nanocomposite makes PPy NW/TiO₂ NTs nanocomposite a promising material for protecting Ti substrate and the coupled 304 stainless steel from corrosion.
