A carbon membrane-mediated CdSe and TiO nanofiber film for enhanced photoelectrochemical degradation of methylene blue.

In this study, a carbon membrane-mediated CdSe and TiO ternary film (CdSe/C/TiO) was prepared to degrade methylene blue (MB). Carbon membrane and CdSe were introduced to the surface of a TiO nanofiber film an hydrothermal deposition process successively. The investigation shows that the carbon membrane not only provides a charge transfer channel to promote the transfer of electron from the conduction band of CdSe to that of TiO, but also improves the poor conduct between the TiO film and electrolyte.
