摘要	A Ag@CuFe_2O_4@TiO_2nanocomposite film with high performance of photogenerated cathodic protection was prepared by hydrothermal and photoreduction methods.The results showed that when the CuFe_2O_4 hydrothermal reaction time was 6 h and the Ag NO_3concentration was 0.1 M,the Ag@CuFe_2O_4@TiO_2nanocomposite material performed the best cathodic protection capability for 304 stainless steel (304SS).In this case,the protective potential achieved-930 m V (versus SCE) associated with the photocurrent density of 475μA/cm~2,which was 14.8 times that of pure TiO_2nanowires.In the dark,the nanocomposite provided cathodic protection of up to 485 m V for 304SS.Due to the heterogeneous junctions at the two interfaces among the three kinds of nanocomposite materials,the build-in electric field was fabricated,which promoted the separation efficiency of photogenerated electrons and holes and effectively improved the photochemical cathodic protection of 304SS.
