GAS SENSOR MEMBER USING NANOSCALE CATALYSTS LOADED HOLLOW METAL OXIDE NANOCAGES USING METAL-ORGANIC FRAMEWORK TEMPLATES AND MANUFACTURING METHOD THEREOF

摘要

The present invention relates to a member for a gas sensor, a gas sensor using the same, and a method of manufacturing the same. More particularly, the present invention relates to a gas sensor using a metal organic structure in which metal nanoparticles are formed by self- The present invention relates to a metal oxide nanocage having a porous hollow structure that is uniformly bonded and functionalized, a member for a gas sensor using the same, a gas sensor, and a manufacturing method thereof. The present invention relates to a method of synthesizing a porous nanomaterial, which is a metal organic structure, by binding a nanoparticle catalyst having a size of 0.1 to 10 nm within the synthesized metal organic structure, and then oxidizing the metal ion of the metal organic structure through heat treatment, And is characterized by a porous hollow-structure metal oxide nanocage structure in which a nanoparticle catalyst is formed by the removal of the ligand. Particularly, since the gas easily diffuses into the porous hollow structure and reacts with the nanoparticle catalyst uniformly bound to the surface of the metal oxide, the sensor characteristic is dramatically increased, and the sensing material group for various gases The present invention can provide a gas sensor member, a gas sensor, and a manufacturing method thereof capable of mass production by simultaneously performing nano particle catalytic binding and hollow structure nanocage formation by a simple process.
