| 20120045574 | HIGH SENSITIVE GAS SENSOR USING CARBON MATERIALS CONTAINING IONIC METAL CATALYST AND MANUFACTURING METHOD THEREOF - Disclosed is a high sensitive gas sensor using a carbon material containing an ionized metal catalyst and a method of manufacturing the same. The method includes the steps of: (1) preparing a hydroxide solution by dissolving a hydroxide in a distilled water; (2) dissolving a metal catalyst in the hydroxide solution; (3) immersing the carbon material in a solution obtained through step (2) and stirring the carbon material; (4) heat-treating a mixture obtained through step (3); (5) cleaning the heat-treated carbon material obtained through step (4); (6) drying the carbon material cleaned through step (5); and (7) manufacturing the gas sensor by loading the carbon material obtained through step (6) on a substrate. The gas sensor having high sensitivity and responsiveness with respect to a target gas even in a normal temperature is obtained. | 02-23-2012 |
| 20110143023 | GAS SENSOR USING POROUS NANO-FIBER CONTAINING METAL OXIDE AND MANUFATURING METHOD THEREOF - Disclosed is a method of manufacturing a gas sensor by using a nano-fiber including metal oxide. The method of manufacturing the gas sensor includes the steps of (1) mixing a polymer precursor with a solvent, (2) dispersing metal oxide into the mixture obtained through step (1), (3) preparing a nano-fiber by performing electro-spinning with respect to the mixture obtained through step (2), (4) oxidizing the nano-fiber obtained through step (3), (5) carbonizing the nano-fiber that has been oxidized through step (4), (6) activating the nano-fiber that has been carbonized through step (5), and (7) manufacturing the gas sensor by depositing the nano-fiber, which has been activated through step (6), between electrodes of a silicon wafer. The gas sensor is manufactured with superior sensitivity at a normal temperature and reliability. | 06-16-2011 |
