【 摘 要 】

Two types of molybdenumâ€�?�carbon nanotubes and molybdenum treated carbon nanotubes/titania composites were prepared using a solâ€�?�gel method. These composites were characterized comprehensively by the Brauerâ€�?�Emettâ€�?�Teller (BET) surface area, scanning electron microscopy (SEM), energy dispersive X-ray (EDX) analysis, X-ray diffraction (XRD), transmission electron microscopy (TEM) and UV-vis absorption spectroscopy. It was found that the photocatalytic degradation of a methylene blue solution could be attributed to the combined effects caused by the photo-degradation of titania, the electron assistance of carbon nanotube network, and the enhancement of molybdenum. The proposed redox mechanism of the photodegradation of methylene blue on Mo-CNT/TiO₂ composites is suggested.
