GAS SENSOR AND MEMBER USING METAL OXIDE SEMICONDUCTOR NANOTUBES INCLUDING NANOPARTICLE CATALYST FUNCTIONALIZED BY NANO-CATALYST INCLUDED WITHIN APOFERRITIN, AND MANUFACTURING METHOD THEREOF

摘要

The present invention relates to component gas sensor, gas sensor and the method for producing it. Particularly, the present invention relates to a kind of components of gas sensor, it the use of metal oxide/carbon nano-tube composite material include that catalyst is combined thereon, it include to be formed on apoferritin and outer surface one-dimensional nanotube by distribution nanoparticle catalyst, by controlling heating rate, to gas sensor and the method for producing it. According to the present invention, albumen is known as apoferritin and is used as template formation nanoparticle with having a size of 0. with surface charge and polymolecularity1-5 nanometers, and the mixed metal oxide precursors of the nanoparticle catalyst formed/mixed with polymers electrospun solution carries out Electrospun, and catalyst is allow to be assigned to the uniform of composite nano fiber. In addition, controlling heat treatment process during the rate of heat addition to form metal oxide nanotubes structure includes that nano particle is evenly distributed catalyst thereon and utilizes Ostwald ripening phenomenon. Gas sensitivity is high, can detect part per billion) increase reaction surface area that micro gas about 100 is controlled by catalytic action and shape, the characteristic of these key factor gas sensors. In addition, the gas sensor have it is highly selective, with allow detect multiple gases, pass through change composition material. It combines simultaneous with shape control nanotube furthermore it is possible to carry out catalyst by simple, passes through control electrospinning and heat treatment process. It is, therefore, possible to provide a component, the gas sensor that can produce in enormous quantities, gas sensor and the method for producing it. ;The 2016 of copyright KIPO submissions
