Gas detection composite comprising CEO2 uniformly loaded on oxide nanostructure and method of preparation thereof
The present invention relates to a composite having the ability to stably and reliably detect a target gas even in a moist environment. The composite of the present invention includes: a nanostructure of an oxide semiconductor selected from the group consisting of SnO2, ZnO, WO3, NiO, and In2O3; and a CeO2 additive loaded on the nanostructure. The oxide semiconductor nanostructure is uniformly loaded with CeO2. The composite of the present invention can rapidly detect an analyte gas with high gas response irrespective of the presence and concentration of moisture. The present invention also relates to methods for preparing the composite, a gas sensor including the composite as a material for a gas sensing layer, and a method for fabricating the gas sensor.
