摘要: 以Ti(OC₄H₉)₄、In(NO₃)₃和聚乙烯吡咯烷酮(PVP-K30)为原料,采用静电纺丝技术制备了In₂TiO₅纳米带。利用X射线衍射(XRD)、扫描电子显微镜(SEM)、紫外-可见漫反射光谱(UV-Vis DRS)和N₂吸附-脱附等技术对不同焙烧温度处理得到的样品进行表征,详细研究了焙烧温度对In₂TiO₅纳米带晶粒尺寸、形貌、比表面积和孔径的影响。以20 mg·L^-1的氟喹诺酮类抗生素左氧氟沙星(LEV)为目标降解物,125 W高压汞灯为光源,评价了不同焙烧温度下In₂TiO₅纳米带的光催化活性。结果表明,焙烧温度对In₂TiO₅的形貌与光催化活性有明显影响。当焙烧温度为800℃时,制备的In₂TiO₅纳米带表面光滑,其宽度为(552±58) nm、厚度约为140 nm,光催化活性最强,光照60 min,LEV的降解率可以达到95%。

Abstract: In₂TiO₅ nanobelts were fabricated by means of electrospinning using Ti(OC₄H₉)₄、In(NO₃)₃ and polyvinyl pyrrolidone(PVP-K30) as raw materials. The nanobelts calcined at different temperature were characterized by XRD, SEM, UV-Vis DRS and N₂ adsorption-desorption isotherms. The influences of the calcination temperatures on the crystallite size, morphology, BET specific surface area and pore size of In₂TiO₅ nanobelts was studied. The photocatalytic activity of the as-prepared In₂TiO₅ nanobelts was evaluated by the photocatalytic degradation of levofloxacin (LEV) of fluoroquinolone antibiotics under the irradiation of the high pressure mercury lamp (125 W). The results show the significant effect of calcination temperature on the morphology and photocatalytic activity of In₂TiO₅ nanobelts. When the calcination temperature is 800℃, the In₂TiO₅ nanobelts prepared exhibit the best photocatalytic activity with smooth surface, the width of (552±58) nm and thickness of 140 nm. The degradation rate of LEV can be up to 95% after 60 min of irradiation.
