以偏钛酸和浓硫酸为原料，采用水热法，以不同的有机酸为改性剂，合成了尺寸可控的纯金红石相TiO{sub 2}纳米棒。采用X射线衍射（XRD）和透射电子显微镜（TEM）对合成的金红石型TiO{sub 2}纳米棒进行了表征。研究了有机酸改性剂对金红石型TiO{sub 2}纳米棒尺寸的影响。结果表明，有机改性剂的空间位阻效应和有机酸的非极性有利于小尺寸金红石型TiO{sub 2}纳米棒的形成。改性剂的羧基（或羟基）与纳米TiO{sub 2}表面之间存在强烈的配位作用，有效地抑制了纳米TiO{sub 2}晶体的生长。
Size-controlled synthesis of pure rutile-phase TiO{sub 2} nanorods was carried out by a hydrothermal method using different organic acids as modifiers, and metatitanic acid and concentrated sulfuric acid as raw materials. The synthesized rutile TiO{sub 2} nanorods were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The effects of organic acid modifiers on the sizes of rutile TiO{sub 2} nanorods were investigated. It was found that the steric effect occurred by the organic modifiers and non-polarity of organic acids were beneficial to the formation of small-sized rutile TiO{sub 2} nanorods. The strongly coordinative interaction between the carboxyl (or hydroxyl) group of the modifier and the surface of TiO{sub 2} nanoparticles effectively inhibited the crystal growth.
