摘要/Abstract

摘要：

以聚乙烯吡咯烷酮(PVP)为纤维骨架, 乙醇为溶剂, 乙酸锌[Zn(CH₃COO)₂·2H₂O]和三乙酰丙酮铁(C₁₅H₂₁O₆Fe)为原料, 利用静电纺丝技术结合溶胶-凝胶法制备前驱体纤维, 经焙烧后得到不同摩尔比的FTO导电玻璃负载Fe₂O₃/ZnO复合光电极(Fe₂O₃/ZnO/FTO). 利用热重-差热分析仪(TG-DTA)、 X射线衍射仪(XRD)、扫描电子显微镜(SEM)和X射线光电子能谱仪(XPS)等对材料进行了表征, 以亚甲基蓝(MB)为目标降解物, 探讨了复合材料的光电催化活性. 结果表明, Fe₂O₃与ZnO的复合能够有效构建p-n异质结, 利于光生电子和空穴的分离, 其光电催化性能较纯ZnO/FTO和Fe₂O₃/FTO均有明显提高; 不同n(Fe)/n(Zn)的复合光电极表现出了不同的光电催化活性, 在相同催化时间内, 当n(Fe)/n(Zn)=1:1时, Fe₂O₃/ZnO/FTO对MB催化活性最佳, MB的降解率达到97%.

Abstract:

Using polyvinylpyrrolidone(PVP) and ethanol as fiber skeleton and solvent, respectively, Fe₂O₃/ZnO precursor fibers were prepared by sol-gel method combined with electrospinning technique with zinc acetate [Zn(CH₃COO)₂·2H₂O] and three iron acetylacetonate(C₁₅H₂₁O₆Fe) as raw materials. Fe₂O₃/ZnO/FTO composite photoelectrodes with different Fe/Zn molar ratios were obtained by calcination. The morphologies and chemical components were characterized by thermogravimetry-differential thermal analysis(TG-DTA), X-ray diffraction(XRD), scanning electron microscopy(SEM), X-ray photoelectron spectroscopy(XPS), and so on. The photoelectrocatalytic performance of the obtained sample was tested by the degradation of methylene blue(MB) solution. The results indicate that the p-n heterojunctions between ZnO and Fe₂O₃ are beneficial for separation of photogenerated electrons and holes, resulting in Fe₂O₃/ZnO/FTO with high catalytic activity in comparsion with ZnO/FTO and Fe₂O₃/FTO. The composite photoelectrodes with different Fe/Zn molar ratios exhibit different photoelectrocatalytic activity. When n(Fe)/n(Zn) is 1:1, the catalytic activity of Fe₂O₃/ZnO/FTO is the optimal, the degradation rate of MB is 97% after 140 min.
