摘　　要：采用静电纺丝法制备基于聚丙烯腈纳米纤维的氯化血红素催化材料(hemin/PAN纤维膜),并经偕胺肟改性和Cu^(2+)离子金属配位反应分别获得hemin/AOPAN和Cu-hemin/AOPAN。为了证实Cu-hemin/AOPAN的成功制备,使用扫描电子显微镜(SEM)、傅立叶变换红外光谱仪(FTIR)和X射线能谱仪(EDS)对三者的纤维形貌及分子结构进行了表征,并通过罗丹明B(RhB)降解反应测试了Cu^(2+)对hemin/AOPAN纤维膜催化性能的影响。结果表明,Cu-hemin/AOPAN纤维表面有明显的层状附着物,其红外光谱中对应N-H/O-H的基团宽化,说明铜离子通过配位反应负载于纤维表面。此外,在0.1 mol/L铜离子配位反应溶液中获得的Cu-hemin/AOPAN纤维膜,仅需30 min左右即可完成对RhB染液的氧化降解,相比hemin/AOPAN的催化性能提升约2.2倍,证实了Cu^(2+)对hemin/AOPAN纤维膜催化性能的提升作用。Electrospinning was carried out to prepare hemin/PAN fibrous membranes,and the amidoxime modification and metallic coordination by Cu^(2+)ions were processed to obtain hemin/AOPAN and Cu-hemin/AOPAN,respectively.SEM,FTIR,EDS were conducted to analyze the morphology and molecular structure of the prepared samples,while the photocatalytic performance affected by copper ions were tested by RhB degradation.The result showed that,lamellar adhesions were found on the surface of Cu-hemin/AOPAN and N-H/O-H group broadening was found in FTIR spectra,indicating the copper ions were successfully supported on the hemin/AOPAN membranes.Furthermore,the Cu-hemin/AOPAN prepared with the copper ions solution of 0.1 mol/L degraded the RhB solutions within 30 mins,exhibiting 2.2 times catalytic performance than that of the hemin/AOPAN.
