摘要：通过调节纺丝前驱体浓度采用静电纺丝法制取纯相BiFeO_3,得到分别经过500℃、600℃、700℃热处理产物,使用X射线衍射仪(XRD)和扫描电镜(SEM)等对样品进行表征以确定最佳热处理温度,以期制得纯度较高、结构较为完整的BiFeO_3纤维,随后,以水体主要污染物之一——亚甲基蓝(MB)为目标污染物,在可见光催化下,测定分别经过不同温度热处理的BiFeO_3样品对亚甲基蓝的降解率,以测定产物对亚甲基蓝的可见光催化效率。
The pure phase BiFeO3 was prepared by the method of electrospinning by adjusting the spinning precursorconcentration. The samples were heated at 500 益, 600 益 and 700 益, respectively. The samples were characterized byX-ray diffraction （XRD） and scanning electron microscopy （SEM） to determine the optimum heat treatment temperature,in order to obtain high purity, relatively complete structure of BiFeO3 fiber, followed by one of the main waterpollutants- - -methylene blue （ MB） as the target pollutants, in visible light catalysis, the measured by differenttemperature heat treatment of BiFeO3 sample on the degradation rate of methylene blue to determine the product ofmethylene blue visible light catalytic efficiency. In addition, the samples were characterized by methylene blue （MB） astarget pollutants, in order to study their visible light catalytic efficiency.
