摘要
采用水热合成法制备了无机半导体光催化剂二硫化钼(MoS_(2)),利用静电纺丝技术,将MoS_(2)粉末添加到不同质量分数的聚丙烯腈(PAN)溶液中进行共混纺丝,制备MoS_(2)/PAN复合纳米纤维膜,并用于罗丹明B溶液的催化降解。借助扫描电子显微镜(SEM)、透射电子显微镜(TEM)、X-射线衍射(XRD)等对纳米纤维膜的形貌和性能进行表征。结果表明:MoS_(2)/9%PAN复合纳米纤维膜中的纳米纤维形貌较好,直径较均匀,MoS_(2)在纳米纤维上的分布也较为均匀;使用其对30 mL的10 mg/L罗丹明B溶液进行光催化降解,光催化效果好,降解率达89.8%,重复使用3次后,降解率仅下降了2.3%,表现出良好的循环使用性。
The inorganic semiconductor photocatalyst molybdenum disulfide(MoS_(2))is prepared by hydrothermal synthesis.MoS_(2) powder is added to polyacrylonitrile(PAN)solution with different mass fraction by electrospin⁃ning technology,and MoS_(2)/PAN composite nanofiber membrane is prepared and used for catalytic degradation of Rhodamine B solution.The morphology and properties of nanofiber membrane are characterized by scan⁃ning electron microscopy(SEM),transmission electron microscopy(TEM)and X-ray diffraction(XRD).The re⁃sults show that the morphology of MoS_(2)/9%PAN composite nanofiber membrane is good,the diameter is more uniform,and the distribution of MoS_(2) on the nanofiber is also uniform.30 mL of 10 mg/L Rhodamine B so⁃lution is photocatalytic degraded by MoS_(2)/9%PAN composite nanofiber membrane.The MoS_(2)/9%PAN compos⁃ite nanofiber membrane shows good photocatalytic effect with 89.8%of degradation rate,and degradation rate decreased by only 2.3%after repeated use for 3 times,showing good recycling.
