A novel method based on the reaction between Mg foil and water in the presence of NaCl has been employed to synthesise one‐dimensional (1D) Mg(OH) 2 nanostructures. It is found that the presence of NaCl not only increases the reaction rate but also results in the formation of 1D Mg(OH) 2 nanostructures with their morphologies being related to the NaCl concentration. Nanorods with 100–400 nm in width and more than 1 μm in length are observed when the NaCl concentration is low, whereas nanowires with 20–120 nm in diameter and several micrometres in length and their self‐assembled nest‐like structures are formed in the case of high NaCl concentration. The authors’ results have also shown that both nanorods and nanowires grow along the [110] direction. Based on experimental observations, a possible mechanism is proposed for the growth of 1D Mg(OH) 2 nanostructures and their self‐assembled structures.
