GAS SENSING LAYERS USING METAL OXIDE NANOCUBE WITH P-N JUNCTION AND HOLLOW STRUCTURE CONTAINING NANOPARTICLE CATALYST BASED ON METAL ORGANIC STRUCTURE USING GALVANIC SUBSTITUTION REACTION 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 manufacturing method thereof. More particularly, the present invention relates to a first metal oxide hollow nanocube having a p-type characteristic including a nanoparticle catalyst made using a metal organic structure A gas sensor, and a method of manufacturing the same. 2. Description of the Related Art [0002] In recent years, nanoscale nanoscale nanotubes have been developed. In particular, the present invention can synthesize an n-type hollow nanocube structure, which is difficult to synthesize based on a conventional metal organic structure material, by using a chemical reaction called a galvanic substitution reaction, and a hollow nanocube Can be mass-produced by an easy solution process method in combination with a good sensitivity characteristic capable of detecting a very small amount of gas based on a wide specific surface area and an activated catalyst property, thereby providing an effective gas sensor member, a gas sensor, Can be started.
