    Abstract: PURPOSE: A metal oxide-carbon particle-carbon nanofiber composite is provided to cause polarity on the surface, to ensure high porosity, and to draw synergistic effect of a carbon fiber precursor such as metal alkoxide which effectively store ions and PAN(poly(acrylonitrile)) with excellent mechanical property. CONSTITUTION: A metal oxide-carbon particle-carbon nanofiber composite contains metal oxide and carbon particles which are uniformly dispersed. A method for preparing the composite comprises: a step of preparing a spinning solution containing metal alkoxide(M(OR)_n), the carbon particles, a carbon fiber precursor; a step of electrospinning the spinning solution to obtain a precursor spun fiber; a step of oxidizing and stabilizing the spun fiber to obtain flame retardant fiber; and a step of carbonizing the flame retardant fiber.

    Abstract: An activated carbon with ultra-high specific surface area which is prepared using corn, which has a specific surface area of 2500 m^2/g or more and an average pore size of about 2 nm, and in which a ratio of micropores to mesopores is controllable is provided, a method for preparing the activated carbon inexpensively and easily is provided, and various uses of the activated carbon including odor removal, water purification, natural gas adsorption, electric double layer supercapacitors, and catalyst carriers are provided. As a method for preparing an activated carbon with ultra-high specific surface area using corn grains, a method for preparing an activated carbon with a specific surface area of 2500 m^2/g or more using corn comprises the steps of: (A) drying and sorting raw material; (B) carbonizing the sorted raw material to a temperature of 500 to 1000 deg.C in an inert gas atmosphere; (C) mixing at least one activating agent selected from potassium hydroxide, sodium hydroxide, calcium carbonate, and zinc chloride with the carbide to activate the carbide, and controlling sizes of mesopores and micropores of the carbide while controlling content, activating time and activating temperature of the activating agent; and (D) cleaning and drying the size-controlled activated carbide. The step(B) is performed by carbonizing the raw material at 550 to 650 deg.C for 1 to 2 hours at a temperature rising rate of 5 deg.C/min. The step(C) is performed by activating the carbide at 700 to 1000 deg.C for 30 to 300 minutes using the activating agent to the carbide at a weight ratio of 1:1 to 5. The cleaning process in the step(D) is repeated until the cleaned carbide has a potential of hydrogen(pH) of 6 to 8.
