Magnesium-aluminum alcoholate nanowire as well as preparation method and application thereof

The invention discloses a magnesium-aluminum alcoholate nanowire as well as a preparation method and application thereof. The invention belongs to the field of nano functional materials. The invention aims to solve the technical problems of harsh reaction conditions, tedious preparation steps and high operation difficulty of the existing preparation method of the metal nanowire. The method comprises the following steps: cutting the Mg-Al-Li alloy into blocks, adding the blocks into anhydrous isopropanol, and heating at the constant temperature of 65-75 DEG C for 22-24 hours; the Mg-Al-Li alloy serves as a reaction base material, Mg-Al reacts to form Mg17Al12, electron transfer is accelerated through the electron effect between metal, in addition, a geometric effect exists between magnesium and aluminum alloy, a new active site can be formed at a two-phase interface between magnesium and aluminum metal, therefore, the reaction efficiency is remarkably improved, the reaction time is shortened, and the preparati
