摘　　要：通过溶胶-凝胶和物理研磨混合的方法制备了具有吸附和光催化双重性能的芦苇-碳纳米管掺杂的二氧化钛复合材料。将该材料用来处理甲醛溶液,研究芦苇比例、煅烧温度以及复合材料用量等因素对处理效果的影响。结果显示,氙灯照射3 h,芦苇复合比为1∶9、纳米管掺杂比0.1%且500℃煅烧的芦苇-碳纳米管掺杂二氧化钛复合材料,对10 mg/L的甲醛溶液的脱色率达到98.5%。Reed-carbon nanotube-doped titanium dioxide composite material with dual adsorption and photocatalytic properties was prepared by ere prepared by sol-gel and physical grinding.The composite material was used to treat formaldehyde solution,and the factors such as the ratio of reed,calcination temperature and the amount of composite material had influence on the treatment effect.The composite material with reed ratio 1:9,carbon nanotube doped ratio 0.1%was calcined at 500℃,and the decolorization rate of the formaldehyde solution of 10 mg/L reached 98.5%.
