采用水溶液/CTAB/正丁醇/庚烷四组分组成的反相胶束体系,制备了MnOOH纳米棒,并用透射电镜(TEM)、高分辨透射电镜(HRTEM)和X射线粉末衍射(XRD)进行了表征.结果显示所得MnOOH为单斜晶系,直径约为10 nm、长度约为200 nm.实验表明,不同的反应时间所得纳米棒的长度不同,但直径可以保持不变.

MnOOH nanorods were synthesized in quaternary water/oil (W/O) microemulsion solution containing CTAB, n-butanol, heptane and water. Transmission electron microscopy (TEM) and high resolution transmission electron microscopy (HRTEM), electron diffraction analysis (ED) and X-ray diffraction (XRD) were utilized to characterize the shape, size and structure of the obtained products. The results show that the nanorods were monoclinic manganese oxyhydroxide, which were about 10 nm in diameter and more than 200 nm in length. Moreover, the length of nanorods increased with the increase of reacting time, while the diameter had no change.

Key words: MnOOH nanorod, CTAB, reverse micelle
