Substrate-independent and catalyst-free synthesis of magnesium nanowires.

ABSTRACT: We report a catalyst free and substrate independent synthesis of magnesium nanowires using a simple thermal evaporation method. The produced Mg nanowires have a size of 8-60 nm with a crystalline MgO shell of ∼2-5 nm thickness. The synthesized nanowires grow along the [001] direction and horizontal to the substrate. Moreover, from ex situ TEM investigation the various sequential stages involved in the nanowire formation process were identified. The experimental outcome indicates the sequential stages including (i) formation of Mg nanoparticles, (ii) coarsening of Mg nanoparticles to microparticles via deposition diffusion aggregation (DDA) and the orientation attachment (OA) process, and (iii) nucleation and growth of Mg nanowires. In depth analysis confirms two types of nano
