Abstract
Disclosed are a chemochromic nanoparticle, a method for manufacturing the chemochromic nanoparticle, and a hydrogen sensor comprising the chemochromic nanoparticle. In particular, the chemochromic nanoparticle has a core-shell structure such that the chemochromic nanoparticle and comprises a core comprising a hydrated or non-hydrated transition metal oxide; and a shell comprising a transition metal catalyst.
Claims4
A method for manufacturing a chemochromic nanoparticle, the method comprising:
- preparing a hydrated or non-hydrated transition metal oxide;
- preparing a metal catalyst solution by dissolving a metal catalyst precursor and a polymer compound in an organic solvent;
- preparing a mixed solution by adding the hydrated or non-hydrated transition metal oxide to the metal catalyst solution;
- manufacturing the chemochromic nanoparticle with a core-shell structure by irradiating the mixed solution with UV light;
- and
- obtaining the chemochromic nanoparticle by filtering the mixed solution, wherein the ratio between the metal catalyst precursor and the hydrated or non-hydrated transition metal oxide in the mixed solution is 8:10 to 8:12 by weight.
