Abstract  

MWCNT/TiO2 composite film was prepared on the surface of the 304 stainless steel by the sol-gel technology and spin coating method. The phase and morphology of the composite film were measured by the X-ray diffraction and the electron microscope. The photocathodic properties of the composite film for the 304 stainless steel under UV and white light were analyzed by the electrochemical tests. The results indicated that the composite film containing the carbon nanotubes with the size of 20~40 nm and heated under 450℃ has the better photoelectric property either irradiated by UV light or white light corresponding to that of pure TiO2 film. At the same time, it was also indicated that the addition of MWCNT into TiO2 film could enhance the photocathodic property for 304 stainless steel either in 3% NaCl solution or in the seawater.

Key words:  TiO2      carbon nanotubes      sol-gel      photocathodic property
