摘　　要：多级结构纳米材料以其形貌多样、比表面积大、空间利用率高以及易于界面传输和吸附富集等特性,在能源催化转化和环境保护等相关领域受到广泛关注.多级结构材料可通过溶剂热合成法、模板法、自组装法、静电纺丝技术等方法合成制得,其中静电纺丝技术是一种简单可控的方法,且可以根据需求构建具有不同成分以及复杂内部和外部结构的纳米纤维.基于此,本文总结了近几年来利用静电纺丝技术制备不同结构的纳米纤维材料的研究进展,详细介绍了中空型、wire-in-tube型、tube-in-tube型、多通道型和树枝状型多级结构纳米纤维材料的制备方法,重点关注了多级结构纳米材料在污染物的降解、环境修复等环境催化领域的应用,并对当前静电纺丝技术构建适用于环境催化领域的多级结构纳米材料面临的挑战和未来的研究方向进行了展望.The hierarchical structure nanomaterials have the characteristics of diverse morphology,large specific surface area, high space utilization, easy interface diffusion and adsorptive preconcentration, which have received great attention in the catalytic conversion of energy and environmental protection. It can be synthesized by solvothermal method, template method, selfassembly method, electrospinning technology and other methods. Electrospinning technology has been considered as one of simple and controllable methods, which can construct nanofibers with different compositions and complex internal and external structures as required. Herein, the recent progresses in the preparation of nanofibers with different structures by electrospinning technology have been discussed in detail, including hollow nanofibers, wire-in-tube nanofibers, tube-in-tube nanofibers, multi-channel nanofibers and branched nanofibers, especially in the application of environmental catalysis such as pollutant degradation and environmental remediation. Furthermore,the prospects for the challenges and research directions of designing hierarchical structure nanomaterials by electrospinning technology were proposed to shed light on further development of environmental catalysis in future.
