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.

Method for manufacturing chemochromic nanoparticles

A hydrogen sensor and a method for manufacturing the same are provided. The hydrogen sensor includes a metal oxide layer formed over a substrate, and a catalytic pattern that is formed over the metal oxide layer. Further, a protective layer is formed over the catalytic pattern.

Hydrogen sensor and method for manufacturing the same

Disclosed are a hydrogen detection sensor and a method of manufacturing the same. The hydrogen detection sensor is manufactured by using hydrothermal synthesis method to synthesize a molybdenum oxide (MoO) nanostructure, and irradiating UV light thereon to form an MoO&#x2014;Pd nanocomposite comprising the molybdenum oxide nanostructure with palladium (Pd) catalyst particles, and coating the MoO&#x2014;Pd nanocomposite on a substrate. As such, a visible color change from the MoObefore and after exposure to hydrogen may be so obvious that the sensing or sensitivity of hydrogen and the long-term stability may be substantially improved. In addition, the manufacturing process is simple, and the manufacturing costs may be reduced.

Color changeable hydrogen detection sensor based on molybdenum oxide and method of manufacturing the same

Disclosed herein is a hydrogen detecting sensor that includes a sulfide-metal catalyst, such that hydrogen gas can be detected visibly with naked eyes. Particularly, the hydrogen detecting sensor includes a substrate, a sulfide layer formed on the substrate and chemically discolored when exposed to hydrogen, and a metal catalytic layer formed on the sulfide layer.
