Abstract
The present application relates to a composite structure, a method of manufacturing the composite structure, and a catalyst including the same. In the composite structure of the present application, metal nanoparticles having a very small size are uniformly formed at a high density regardless of a type of metal. The method of manufacturing the composite structure of the present application can quickly prepare the composite structure in which metal nanoparticles having a very small size are formed uniformly at a high density regardless of the type of metal.
Claims9
A composite structure comprising:
- a cellulose-derived carbon layer;
- and
- a metal layer present on the cellulose-derived carbon layer,
- wherein the metal layer includes metal nanoparticles,
- wherein metal of the metal nanoparticles is at least one selected from the group consisting of Ni, Co, Au, Fe, Pt, Pd, Ag, Si, Ir, Cu, Ru, Rh, Sn, Zn, Ce, Hf, Ti and Mn,
- wherein the cellulose-derived carbon layer includes carbon nanoclusters having an aromatic ring, and
- wherein a ratio (IG/ID) of a peak intensity (IG) within a wavenumber range of 1550 cm−1 to 1600 cm−1 of a Raman spectrum of the cellulose-derived carbon layer and a peak intensity (ID) within a wavenumber range of 1300 cm 1 to 1400 cm 1 of a Raman spectrum of the cellulose-derived carbon layer is 2.2 or less.
