Abstract: Dispersive nanoparticles and whiskers have been extensively studied owing to their unique properties and potential applications. Solution-based synthesis methods, especially hydrothermal routes, are widely employed to produce nanomaterials because of their relative simplicity and low energy consumption. Herein the recent progress of hydrothermal technologies in the synthesis of dispersive nanoparticles are introduced firstly, including supercritical hydrothermal route, continuous hydrothermal route and hydrothermal modification route. The mechanisms for controlling the nanoparticle size and dispersion are discussed. Then two novel approaches to the hydrothermal fabrication of whiskers are introduced, including hydrothermal recrystallization method and ion induction-structural reforming method, the mechanism for the oriented growth of the whiskers is also discussed.

Key words: nanoparticles, whiskers, hydrothermal, dispersion, oriented growth
