摘要
氧化铋(Bi_2O_3)纳米纤维是一种新型的无机功能半导体材料,近年来在光催化降解废水、光敏元件、生物传感器、防辐射材料等领域中彰显出巨大潜能。阐述了静电纺丝法制备Bi_2O_3纳米纤维的形成机理及其主要影响因素。针对单一Bi_2O_3纳米纤维光催化活性不高和抗腐蚀性较差的不足,详细综述了通过掺杂改性及复合半导体改性对Bi_2O_3纳米纤维的改性研究进展,指出改性后的Bi_2O_3纳米纤维具有更广阔的应用前景。在此基础上,提出了当前Bi_2O_3纳米纤维研究工作中存在的主要问题,并对其今后的发展进行了展望。
As a novel inorganic functional semiconductor material,bismuth oxide( Bi_2O_3) nanofibers exhibit potential application in the field of photocatalytic degradation of wastewater, photosensitive element,biosensor and radiation-proof material in recent years. The formation mechanism and main influencing factors of Bi_2O_3 nanofibers prepared by electrospinning were described. In order to overcome the poor photocatalytic activity and corrosion resistance of single Bi_2O_3 nanofibers,the progress on the modification of Bi_2O_3 nanofibers by doping and compound semiconductor was summarized in detail,and the modified Bi_2O_3 nanofibers unfold broader application prospects was discussed. Furthermore,the main problems existing in the current research work of Bi_2O_3 nanofibers were proposed and the further research prospects were presented.
