Research Progress in Morphology-Controllable Hydrothermal Synthesis of TiO2 Nanostructures

本文综述了水热法制备纳米材料的特点以及用此法制备不同形貌的TiO2纳米粉体的研究现状，包括零维(纳米颗粒)、一维(纳米线、纳米管等)、二维(纳米片、纳米薄膜等)、三维(纳米花)等，分别阐述了不同形貌TiO2纳米材料已经取得的研究工作，展望了水热法制备纳米材料发展前景及将来需要解决的关键问题。 In the paper, features of hydrothermal method for preparation of nanomaterials and research progress of TiO2 nanoparticles with different morphology were summarized, including zero-di- mension (nano-part icles), one-dimension (nanowires, nanobutes et al.), two-dimension (nano-sheets, nanofilms et al.) and three-dimension (nanoflowers et al.). The progress of different morphology of TiO2 nanomaterials was stated. The prospect of hydrothermal method as well as the existing problems in the future was discussed.
