Hydrothermal synthesis of single crystal mesoporous LiAlO2 nanobelts

Lithium aluminate (α-LiAlO2) nanobelts with the length of 1–2 μm and the thickness of about 25 nm have been successfully synthesized by a hydrothermal method with template assisted. The structure and morphology of the as-prepared products are characterized by X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. Each nanobelt is single crystal structure, and many mesopores are discovered on the surface of the nanobelts. Nitrogen sorption measurements reveal that obtained products exhibited high BET specific surface area up to 224 m2/g and pore volume of 0.72 cm3/g. The growth mechanism of the nanobelts is proposed and the influence of pH value on the morphology is discussed.
