摘    要:TiO2是一种重要的多功能无机材料,一维纳米TiO2材料的可控合成是一个十分复杂的过程。由于一维纳米TiO2材料的存在形式多样(包括纳米纤维、纳米丝、纳米带、纳米棒、纳米线和纳米管等),其可控合成的工艺方法也很丰富。综述了一维纳米TiO2材料可控合成的各种方法,包括静电纺丝法、水热合成法、模板法和阳极氧化法等;分析合成过程中参数变化对所合成纳米材料结构和形貌的影响规律;回顾和总结了近年来一维纳米TiO2材料应用的研究进展;对一维纳米TiO2可控合成的研究和应用进行展望,为进一步拓展一维纳米TiO2的存在形式和应用范围提供参考。

Abstract: TiO2 is one of the most important inorganic materials for its multiple applications. The controllable synthesis of one-dimensional nanostructured TiO2 (1D-TiO2) is a very complex process due to the various morphologies of the 1D-TiO2, such as 1D-TiO2 nanofiber, nanowire, nanobelt, nanorod, nanoribbon, nanotube. Researchers all around the world have developed a variety of controllable synthesis methods, for instance, electrospinning, hydrothermal treatment, template formation and electrochemical anodization. Recent advances in the controllable synthesis of 1D -TiO2 and their applications are presented in this paper. The influences of the synthesis parameters on the structures and morphologies of the as-prepared nanomaterials are systematically analyzed during the controllable synthesis process. And we also present the future development of the 1D -TiO2, providing a reference for the potential morphologies and applications of the 1D-TiO2 nanomaterials.
