摘要：
A new type of photocatalysts MWCNTs/TiO2-NTs nanocomposites prepared by combining multi-walled carbon nanotube(MWCNTs) with TiO2-derived nanotubes were synthesized by a modified hydrothermal method. The SEM,XRD,UV-Vis and TG-DTG were used to characterize its property. The produced MWCNTs/TiO2-NTs nanocomposites were used as the catalysts for photo-degradation of aquatic humic substances,Their photocatalytic efficiency was evaluated by the photodegradation of humic acid in an aqueous solution under ultraviolet light irradiation. The results show MWCNTs could enhance the activity of the photocatalysts;the best degradation efficiency was obtained by using MWCNTs/TiO2-NTs nanocomposites containing 20% MWCNTs as the photo-catalyst.
