Mesoporous materials are eliciting considerable research interest for their application in catalysts and electrodes. In this paper, we report the synthesis of mesoporous alpha-LiAlO2 via a hydrothermal route using through-hole anodized aluminum oxide (AAO) as templates. Crystal structures and morphologies were investigated by X-ray diffraction (XRD) and scanning electron microscopy (SEM). alpha-LiAlO2 reproduced the one-dimensional structures of AAO templates and obtained two kinds of nanostructures, namely, nanoparticles and nanoflakes. Extremely high specific surface area of up to 117.3 m(2)/g and large pore volume of 0.87 cm(3)/g were confirmed by nitrogen-sorption measurement, which shed light on the potential practical application of mesoporous alpha-LiAlO2.
