摘要
通过表面改性的方法,以聚偏氟乙烯(PVDF)电纺纤维为基材,制备氟碳聚合物电纺纤维毡(表面含有羧基基团);在水热条件下,用含有羧基基团的氟碳聚合物电纺纤维毡作为载体,通过羧基基团对金属离子的吸附络合作用,控制半导体粒子在纤维表面的增长和成核,制备2种半导体复合光催化材料;在光化学反应仪中用制得的催化剂催化水产生氢气,初见成效。
Using poly （ vinylidene fluoride） （ PⅤDF） electrospinning fiber as base material, with the method of the surface modification, fluorocarbon polymer containing carboxyl electrospinning fiber felt was prepared. Under hydrothermal conditions, using fluorocarbon polymer containing carboxyl electrospinning fiber felt as the carrier, through the fluorocarbon polymer electrospinning fiber surface carboxyl complexing adsorption of metal ions in the solution, controlling semiconductor particles’ nucleation and growth on the surface of the fiber, two semiconductor composite photocatalytic materials were prepared. Hydrogen was produced from water used the catalyst produced in the photochemical reaction instrument.
