Abstract: Provided are a composite in which metal nanoparticles are evenly dispersed and adsorbed to pores of a support, and a method of preparing the same. An amorphous nanostructure formed of inorganic polymers having a transition metal and a halogen element as a main chain via hydrogen bonding is used as a chemical template for forming the metal nanoparticles. The formed metal nanoparticles are evenly dispersed and adsorbed to the support with pores.

Abstract: Disclosed are amorphous nanostructure and methods of making amorphous nanostructure. The amorphous nanostructure has a transition metal and a halogen element in the main chain, and the transition metal has an oxidation number of +1. In addition, the inorganic polymer forming the amorphous nanostructure forms hydrogen bonding with an adjacent inorganic polymer. The side chain of the inorganic polymer for hydrogen bonding has hydrogen and elements for hydrogen bonding. Through this, various characteristics can be confirmed.

Abstract: Disclosed are: a metal nanostructure having a diameter of 2 nm to 2.5 nm; and a manufacturing method therefor. The formed metal nanostructure is provided as approximately spherical single-crystalline nanoparticles or amorphous alloy nanoparticles. Besides, a nanostructure fabricated in the form of an oxide has a nanoneedle shape. For formation of the metal nanostructure, an amorphous nanostructure is used. A second metal element having a higher standard reduction potential than a central metal constituting the amorphous nanostructure is used in the synthesis of the metal nanostructure.
