PRODUCTION OF NANOSTRUCTURES

摘要

Methods of producing nanowires and resulting nanowires are described. In one implementation, a method includes heating a reaction mixture including (i) a solvent; (ii) a metal-containing reagent; (iii) a templating agent; and (iv) a seed-promoting agent (SPA) that is a source of halide anions, thereby producing a product that includes nanowires of the metal. The solvent includes at least two hydroxyl groups per molecule. A ratio of a concentration of the halide anions in the reaction mixture to an overall concentration of the metal in the reaction mixture, including ionic and elemental metal forms, is up to 10. The heating is carried out at a seeding temperature, followed by a growth temperature that is higher than the seeding temperature.
