Abstract	A capillary-enforced template-based method is described for the preparation of InVO nanotube arrays. Nanotube arrays of InVO were prepared by filling the InVO sol into pores of polycarbonate membranes and pyrolyzing through sintering. Another type of InVO nanotube arrays (InVO/acac) are obtained from the sol with the addition of acetylene acetone (acac). For comparison purposes, InVO films were prepared by drop casting from InVO same sol. Films and the two types of nanotube arrays of InVO annealed at 500°C consist of mixed monoclinic (InVO-I) and orthorhombic (InVO -III) phases. The nanotubes are perpendicular to substrate surface with the outer diameter of ∼200 nm for short InVO nanotubes and -170 nm for long InVO nanotubes. InVO/acac nanotube array has the highest charge capacity (790 mAh/g), followed by InVO nanotube array (600 mAh/g) then InVO film (290 mAh/g). Such enhanced lithium-ion intercalation properties are ascribed to the large surface area and short diffusion distance offered by nanostructures and amorphisation caused by acetylene acetone. © 2006 Materials Research Society.
