由于抗生素进入人体不能被自主吸收或代谢,对人体造成了很大的危害,以及对自然环境也造成了恶劣的影响,所以我们急需寻找一种有效的措施来降解抗生素.本文利用水热合成法在玻璃纤维固定BiOI,并负载磷酸银制备Ag3PO4@BiOI@玻璃纤维材料,探究最佳复合比例.通过对四环素进行降解实验,对材料的降解性能和机理进行探究.以玻璃纤维固定纳米材料,避免了粉末型半导体材料的弊端,同时将Ag3PO4 与BiOI符合形成异质结,提高了光生载流子的分离效率,使得更多的电子和空穴参与到反应中去.
Because antibiotics can not be absorbed or metabolized independently into the human body,which has caused great harm to the human body and bad impact on the natural environment,we urgently need to find an effective measure to degrade antibiotics.BiOI was immobilized on glass fiber by hydrothermal synthesis and loaded with silver phosphate Ag3PO4@BiOI@ Glass fiber materials,explore the best proportion.Through the degradation experiment of tetracycline,the degradation performance and mechanism were explored.Fixing nano materials with glass fiber avoided the disadvantages of powder semiconductor materials.At the same time,Ag3PO4 was consistent with BiOI to form heterojunction,which improved the separation efficiency of photo-generated carriers and made more electrons and holes participate in the reaction.
