Study on Photocatalytic Degradation of Methylene Blue by Electrostatic Spinning ZnO/Fe2O3/CNTs Composite Nanofibers
ZnO/Fe2O3/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/Fe2O3/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.
