英文摘要	A Ag@CuFe 2 O 4 @TiO 2 nanocomposite film with high performance of photogenerated cathodic protection was prepared by hydrothermal and photoreduction methods. The results showed that when the CuFe 2 O 4 hydrothermal reaction time was 6 h and the AgNO 3 concentration was 0.1 M, the Ag@CuFe 2 O 4 @TiO 2 nanocomposite material performed the best cathodic protection capability for 304 stainless steel (304SS). In this case, the protective potential achieved -930 mV (versus SCE) associated with the photocurrent density of 475 mu A/cm 2 , which was 14.8 times that of pure TiO 2 nanowires. In the dark, the nanocomposite provided cathodic protection of up to 485 mV 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.
