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.
