PbS-TiO2异质结/电纺纤维复合材料的制备与可见光催化降解甲基橙

摘要

在水热条件下,将PbS-TiO2异质结负载于静电纺丝法制备含羧基的具有纳微米尺寸的电纺纤维上,制备PbS-TiO2异质结/电纺纤维复合光催化材料.通过SEM观察,PbS-TiO2异质结能够较为均匀地负载于电纺纤维之上,将复合材料进行UV-Vis测试,其光吸收范围扩展到可见光区.在可见光照射240min下,对甲基橙溶液降解的残留质量分数为2.59%,低于同等条件下PbS-TiO2异质结粉体,说明其具有很好的可见光催化降解效果.%Using electrospinning to prepare electrospun fiber composite material including carboxyl as a carrier under hydrothermal conditions of that PbS-TiO2 heterojunction was loaded more evenly over the fiber to prepare electrospun fiber Photocatalytic materials.The degradation of methyl orange residual mass fraction was 2.59 % under visible light irradiation for 240 min, lower than PbS-TiO2 heterojunction powder under the same conditions, indicating that the photocatalytic degradation had good results.
