WO3-treated fullerene/TiO2 composites (WO3-fullerene/TiO2) were prepared using a sol-gel method. The composite obtained was characterized by BET surface area measurements, X-ray diffraction, scanning electron microscopy, energy dispersive X-ray analysis, transmission electron microscopy, and UV-vis analysis. A methyl orange (MO) solution under visible light irradiation was used to determine the photocatalytic activity. Excellent photocatalytic degradation of a MO solution was observed using the WO3-fullerene, fullerene-TiO2, and WO3-fullerene/TiO2 composites under visible light. An increase in photocatalytic activity was observed, and WO3-fullerene/TiO2 has the best photocatalytic activity; it may attribute to the increase of the photo-absorption effect by the fullerene and the cooperative effect of the WO3.
WO3 处理的富勒烯/TiO2 复合材料（WO3-富勒烯/TiO2）通过溶胶-凝胶法制备。通过 BET 表面积测量、X 射线衍射、扫描电子显微镜、能量色散 X 射线分析、透射电子显微镜和 UV-vis 分析对所得到的复合材料进行了表征。使用可见光照射下的甲基橙（MO）溶液来确定光催化活性。WO3-富勒烯、富勒烯-TiO2 和 WO3-富勒烯/TiO2 复合材料在可见光下对 MO 溶液表现出优异的光催化降解性能。观察到光催化活性增加，WO3-富勒烯/TiO2 具有最佳的光催化活性；这可能归因于富勒烯增加了光吸收效果以及 WO3 的协同效应。
