摘　　要：以钛酸丁酯为钛源,冰醋酸为水解抑制剂,无水乙醇为溶剂,聚乙烯吡咯烷酮为模板剂,利用静电纺丝技术与焙烧工艺,制备了锐钛矿-金红石混晶的TiO_(2)纳米纤维,研究了焙烧温度对TiO_(2)纳米纤维在不同光源下光催化活性的影响,结果表明,焙烧温度为600℃时所得TiO_(2)纳米纤维具有最佳的光催化活性,光照150 min时,紫外光下罗丹明B的光催化降解率达98%,模拟日光下罗丹明B的光催化降解率为85%.TiO_(2)nanofibers containing anatase and rutile mixed crystalsare prepared,employing electrospinning technology and roasting process,using tetra butyl titanate as the titanium source,glacial acetic acid as the hydrolysis inhibitor,absolute ethanol as the solvent,and polyvinylpyrrolidone(PVP)as the template.The effect of calcination temperature on the photocatalytic activitiesof TiO_(2) nanofibers under different light sources was studied.The results show that the TiO_(2) nanofibers obtained at 600℃have the best photocatalytic activity.Under 150 min of light.The photocatalytic degradation rate of RhB is 98%under ultraviolet light,and the photocatalytic degradation rate is 85%under the simulated sunlight.
