HIGH SENSITIVE GAS SENSOR USING CARBON MATERIAL CONTAINING IONIC METAL CATALYST AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a high sensitive gas sensor using a carbon material containing an ionic metal catalyst and a manufacturing method thereof.

SOLUTION: The manufacturing method includes: a first step (1) of preparing a hydroxide solution by dissolving a hydroxide in a distilled water; a second step (2) of putting a metal catalyst in the hydroxide solution prepared through the first step to dissolve the metal catalyst; a third step (3) of immersing a carbon material in a solution obtained through the second step (2) and stirring the carbon material; a fourth step (4) of heat-treating a mixture obtained through the third step (3); a fifth step (5) of cleaning the heat-treated carbon material obtained through the fourth step (4); a sixth step (6) of drying the carbon material cleaned through the fifth step (5); and a seventh step (7) of manufacturing a gas sensor by loading the carbon material obtained through the sixth step (6) onto a substrate. The gas sensor having high sensitivity and responsiveness with respect to a target gas even in a normal temperature can be obtained.
