HYDROGEN GAS SENSOR AND METHOD FOR MANUFACTURING SAME

WIPO Patent Application WO/2022/211554

A1

The present invention relates to a hydrogen gas sensor and, more particularly, to a hydrogen gas sensor capable of operating at room temperature and having high sensitivity and selectivity to hydrogen gas, and a method for manufacturing same. The hydrogen gas sensor according to the present invention comprises: a metal oxide layer; a first electrode and a second electrode spaced apart from each other on the metal oxide layer; a metal nanoparticle layer positioned in a region at which the first electrode and the second electrode are spaced apart; a polymer layer positioned on the metal nanoparticle layer; and a porous color conversion sensing layer positioned on the polymer layer and containing metal oxide, metal nanoparticles, and silicate.
