A simple aqueous solution-based block-polymer-assisted method was developed for the synthesis of Mg(OH)(2) nanotubes using inexpensive starting materials (MgSO4 and NaOH) with significant advance of bringing down the average outer diameter to the regime below 10 nm. The synthesized nanotubes are found to possess a relatively high specific surface area up to 64m(2)/g, which may suggest their potential value for use in the catalysis field. The Barrett-Joyner-Halenda pore-size distribution plot reveals a bimodal distribution centred at 3.4 and 17.3 nm, which may be from the tunnel cavity and the aggregated pores of Mg(OH)(2) nanotubes, respectively. This method can be widely used to fabricate other inorganic 1D nanostructured materials and easily realized in industrial-scale synthesis.
