Abstract: Pure α-LiAlO₂ nanosheets have been successfully prepared by a simple hydrothermal route without adding any surfactants. The morphology of LiAlO₂ nanosheets was controllable by adjusting the hydrothermal temperature. Hexagonal and rhombus lithium aluminate nanosheets have been obtained at different hydrothermal temperatures of 150°C and 190°C, respectively. The structure and morphology of the products were characterised by X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM) and Transmission Electron Microscopy (TEM). The synthesis procedure provided a simple method to prepare lithium aluminate with high purity. The formation mechanism of the nanostructural lithium aluminate was proposed.
