Hydrothermal synthesis of nanostructured spinel lithium manganese oxide

摘要

Nanostructured spherical spinel lithium manganese oxide (LiMnO) with about 200nm in diameter was synthesized for the first time by mild hydrothermal method. The formation of the nanostructured spheres was through self-assembly of the nanoparticles and nanobelts. The influence of the reaction temperature and the time of formation of the nanostructures have been systematically studied. The thermal stability of the nanostructures has been examined by heating-treatment at different temperatures. Powder X-ray diffraction, transmission electron microscopy, high-resolution transmission electron microscopy, thermogravimetric analysis and inductively coupled plasma-atomic emission spectroscopy were used to characterize the products.
