COMPOSITE FOR DETECTING GAS COMPRISING IN2O3 HOLLOW SPHERES AND CEO2 NANOPARTICLES, METHOD FOR PREPARING THE SAME AND GAS SENSOR INCLUDING THE SAME

摘要

The present invention relates to a composite for detecting gas comprising In_2O_3 spheres and CeO_2 nanoparticles, a method for preparing the same, and a gas sensor including the same. More specifically, the present invention relates to a composite for detecting gas, which comprises: a gas detecting body which comprises hollow In_2O_3; and CeO_2 nanoparticles dispersed on the surface of the gas detecting body, a method for preparing the same, and a gas sensor including the same. According to the present invention, the present invention can provide a gas sensor which shows supersensitivity, high selectivity, and high-speed response without the impact of moisture to a variety of reducing gases.
