Abstract
A nano-composite 10 is described, including: a matrix layer 1 including a solid framework 1a and voids 1b defined by the same, and metal fine-particles 3 immobilized to the solid framework 1a. The framework 1a includes aluminum oxyhydroxide or alumina hydrate and forms a 3D network structure. The metal fine-particles have a mean particle diameter of 3 to 100 nm, with 60% or more having particle diameters of 1 to 100 nm. The metal fine-particles 3 exist in a manner that they are not in contact with one another and neighboring metal fine-particles 3 are apart from each other by a distance equal to or larger than the particle diameter DL of the larger one of the neighboring metal fine-particles 3. The metal fine-particles 3 are 3D-dispersed in the matrix layer 1, wherein each metal fine-particle 3 has a portion exposed in the voids 1b.
