摘　　要：本课题以硫酸钛Ti（SO4）2水溶液为钛源，采用单轴静电纺的技术成功地制备出高产量Gd／TiO2纳米带。运用XRD和FESEM等分析手段对纳米带进行了表征。以糠醛废水为降解物考察了Gd／TiO2纳米带的光催化性能，XRD结果表明，当焙烧温度为700℃时得到锐钛矿和金红石混晶型Gd／TiO2纳米带。TEM及SEM分析结果表明，所得纳米带的宽度约为7μm，厚度约为600nm，纳米带长度〉500μm。光催化实验结果表明，Gd／TiO2纳米带紫外光照6h后糠醛废水的降解率可达86．1％。in this paper, the high yield of Gd/TiO2 was prepared by using titanium sulfate Ti（SO4） 2 aqueous solution as a titanium source,and using the technique of single axis electrospinning.XRD and FESEM were used to characterize the nanoparticles.The photocatalytic activity of Gd/TiO2nanoparticles was investigated with furfural wastewater. The results show that the Gd/TiO2 nanoparticles were obtained when the calcination temperature was 700. TEM and SEM analysis results show that the width of the band is about 7 m, the thickness is about 600nm, the length of the nano band is 〉500μm. The experimental results show that the degradation rate of furfural wastewater by Gd/TiO2 nano band ultraviolet irradiation is 86.1%.
