| Abstract: | A sol-gel method was used to prepare WO3/MWCNT-TiO2 composites.Their photocatalytic activities were evaluated by the degradation of methylene blue (MB) solution under UV light.The catalysts were characterized by X-ray diffraction,specific surface area measurement,energy-dispersive X-ray analysis,transmission and scanning electron microscopy.Aqueous MB solutions of 100 ml were photodegraded by a small amount of the WO3/MWCNT-TiO2 composite under UV light irradiation.The photocatalytic data showed that the WO... |
