摘要
本文采用并行静电纺丝技术及水热法制备了NiO/NiFe_(2)O_(4)/Bi_(2)MoO_(6)复合纳米纤维,通过扫描电子显微镜(SEM)、X射线衍射仪(XRD)和紫外-可见漫反射光谱(UV-Vis DRS),对样品的微观形貌和晶态结构进行了表征。在可见光下以RhB为目标污染物,考察了掺杂不同比例H_(2)O_(2)的NiO/NiFe_(2)O_(4)/Bi_(2)MoO_(6)复合纳米纤维对RhB的光催化降解性能。结果表明,加入0.2mL的H_(2)O_(2),光照6min后,NiO/NiFe_(2)O_(4)/Bi_(2)MoO_(6)的Fenton反应对RhB的降解率达到97%以上。
This study utilized parallel electrospinning technology combined with hydrothermal method to prepare NiO/NiFe_(2)O_(4)/Bi_(2)MoO_(6) composite nanofibers.The micro-morphology and crystalline structure of the samples were characterized by scanning electron microscopy(SEM),X-ray diffraction(XRD)and ultraviolet-visible diffuse reflectance spectroscopy(UV-Vis DRS).Applied rhodamine B(RhB)as the target pollutant,the photocatalytic performance of NiO/NiFe_(2)O_(4)/Bi_(2)MoO_(6) composite nanofibers with varying proportions of H2O2 doping was investigated under visible light.The results show that the Fenton reaction system of NiO/NiFe_(2)O_(4)/Bi_(2)MoO_(6) achieved 98.61%degradation efficiency for RhB within 6min of visible light irradiation when 0.2mL H2O2 was introduced.
