A method of making aluminum alkoxide nanowires is disclosed. In some embodiments, the method includes: (1) treating an alloy comprising aluminum (Al) and lithium (Li) with a reactive solvent to form a porous metal comprising Al; and (2) treating the porous metal with an alcohol-comprising solvent to form the Al alkoxide nanowires. In some embodiments, the reactive solvent has a pK.sub.a value at 25° C. that is less than 15. In some implementations, water is employed as the reactive solvent and ethanol is employed as the alcohol-comprising solvent. Methods of making Al oxide nanowires, Al hydroxide nanowires, an aerogel, and a lithium-ion battery are also disclosed.

A catalyst-free synthesis method for the formation of a metalorganic compound comprising a desired (first) metal may include, for example, selecting another (second) metal and an organic solvent, with the second metal being selected to (i) be more reactive with respect to the organic solvent than the first metal and (ii) form, upon exposure of the second metal to the organic solvent, a reaction by-product that is more soluble in the organic solvent than the metalorganic compound. An alloy comprising the first metal and the second metal may be first produced (e.g., formed or otherwise obtained) and then treated with the organic solvent in a liquid phase or a vapor phase to form a mixture comprising (i) the reaction by-product comprising the second metal and (ii) the metalorganic compound comprising the first metal. The metalorganic compound may then be separated from the mixture in the form of a solid.
