摘要

针对工业废水中高毒性、难降解有机污染物难以彻底去除的问题，开发了高效可见光响应的TiO

基光催化材料。结合静电纺丝技术与高温煅烧，制备了一系列不同Fe

掺杂量（FeCl

质量分数≤ 1.00%）的TiO

纳米纤维膜（Fe/TiO

，

= 1、2、3、4和5），探究了微量Fe

掺杂对材料结构、光学性能和光催化性能的影响。采用FT-IR、SEM、XRD、TGA、UV-DRS和光电流测试等手段对Fe/TiO

进行了表征，并以亚甲基蓝（MB）为模型污染物，在模拟太阳光下评价了其光催化活性。结果表明，Fe

掺杂有效改善了材料纤维形貌连续性，并将光吸收边缘由380 nm（纯Fe/TiO

）红移至410 nm（Fe/TiO

-3和Fe/TiO

-5）；适量掺杂Fe

显著提升了载流子分离效率和材料光催化性能。其中，Fe/TiO

-3（FeCl

质量分数为0.40%）在90 min内对MB的降解率达到97.4%，反应速率常数为0.0283 min

-1

，分别是纯TiO

的2.57倍和7.4倍。机理分析表明，Fe

作为电子陷阱抑制了电子-空穴对复合，其取代TiO

中Ti并引入缺陷中心形成杂质能级，协同促进了载流子的分离与转移，从而促进了·O

Abstract

Addressing the difficulty of completely removing highly toxic and refractory organic pollutants from industrial wastewater

efficient visible-light-responsive TiO

-based photocatalytic materials were developed. A series of TiO

nanofiber membranes with different Fe

doping levels (FeCl

mass fraction ≤ 1.00%)

denoted as Fe/TiO

(

= 1

4 and 5)

were fabricated by combining electrospinning with high-temperature calcination to investigate the effects of trace Fe

doping on the material structure

optical properties and photocatalytic performance. The Fe/TiO

samples were characterized by FT-IR

SEM

XRD

TGA

UV-DRS

and photocurrent measurements. Methylene blue (MB) was employed as a model pollutant to evaluate the photocatalytic activity under simulated solar light. The results demonstrate that Fe

doping effectively improves the continuity of the fiber morphology and redshifts the light absorption edge from 380 nm for pure TiO

to 410 nm for Fe/TiO

-3 and Fe/TiO

-5. Appropriate Fe

doping markedly enhances charge carrier separation efficiency and photocatalytic performance. Among the samples

Fe/TiO

-3 with FeCl

mass fraction of 0.40% achieves an MB degradation efficiency of 97.4% within 90 min

with reaction rate constant of 0.0283 min

-1

which are 2.57 and 7.4 times higher than

those of pure TiO

respectively. Mechanistic analysis indicates that Fe

acts as an electron trap to suppress electron-hole pair recombination; by substituting for Ti in the TiO

lattice and introducing defect centers

impurity energy levels are formed

which synergistically promote charge carrier separation and transfer

thereby facilitating the generation of reactive species such as •O

and •OH. This study provides experimental and theoretical references for the modification of TiO

photocatalysts via trace metal ion doping.
