摘要： A method for fabricating an ultra-sensitive metal oxide gas sensor is disclosed, which comprises the steps of spinning a mixture solution including a metal oxide precursor and a polymer onto a sensor electrode to form a metal oxide precursor-polymer composite fiber; thermally compressing or thermally pressurizing the composite fiber; and thermally treating the thermally compressed or thermally pressurized composite fiber to remove the polymer from the composite fiber. Since the gas sensor includes a macro pore between nanofibers and a meso pore between nano-rods and/or nano-grains, gas diffusion and surface area can be maximized. Also, the ultra-sensitive sensor having high stability in view of mechanical, thermal, and electrical aspects can be obtained through rapid increase of adhesion between the metal oxide thin layer and the sensor electrode.

摘要： The present invention provides a gas sensor, including: a sensor substrate provided with an electrode; and a thin layer of sensor material formed by spraying a solution in which metal oxide nanoparticles are dispersed onto the sensor substrate. The gas sensor is advantageous in that a sensor material is formed into a porous thin layer containing metal oxide nanoparticles having a large specific surface area, thus realizing high sensitivity on the ppb scale and a high reaction rate. Further, the gas sensor is advantageous in that it can be manufactured at room temperature, and the thickness of a sensor material can be easily adjusted by adjusting the spray time, so that a thin gas sensor or a thick gas sensor can be easily manufactured.

摘要： A supercapacitor having a metal oxide electrode and a method for preparing the same. The method comprises preparing a substrate composed of a current collector and a titanium dioxide ultrafine fiber matrix layer formed on the current collector, and electrochemically depositing a metal oxide thin film layer onto the substrate by a constant current potentiometry or a cyclic voltammetric method. Since the metal oxide is uniformly deposited on the substrate having a wide specific surface area with the titanium dioxide ultrafine fiber, a bonding material or a conductive particle need not to be added to the capacitor electrode. Therefore, a resistance of the capacitor electrode is prevented from being increased, and thus a capacitance of the capacitor electrode is prevented from being decreased.
