摘要
采用静电纺丝技术制备ZnO/Fe_(2)O_(3)/CNTs复合纳米纤维材料,并使用场发射扫描电镜对材料形貌进行表征。探究了复合材料中两种氧化物的物质的量比、焙烧温度、染料初始浓度、光催化时间、光源等条件对复合材料光催化降解有机染料性能的影响。结果表明,ZnO/Fe_(2)O_(3)/CNTs复合纳米纤维材料在锌铁物质的量比为2∶1,亚甲基蓝初始质量浓度为15 mg/L,光照时间为3 h,光源为紫外线高压汞灯的条件下降解效果最佳,降解率达到97.07%。该实验结果可为光催化降解亚甲基蓝污水提供一定的参考价值。
ZnO/Fe_(2)O_(3)/CNTs composite nanofiber materials were prepared by electrospinning,and the morphology of the materials was characterized by field emission scanning electron microscopy.The effects of molar ratio,roasting temperature,initial concentration of dye,photocatalytic time and light source of the two oxides on the photocatalytic degradation of organic dyes in the composites were investigated.The results showed that the ZnO/Fe_(2)O_(3)/CNTs composite nanofiber materials had the best degradation effect under the conditions of Zn-iron molar ratio of 2∶1,initial concentration of methylene blue of 15 mg/L,illumination time of 3 h,and ultraviolet high-pressure mercury lamp,with a degradation rate of 97.07%.The experimental results can provide a certain reference value for the photocatalytic degradation of methylene blue wastewater.
