Abstract
A method for fabricating a porous carbon is provided. The method comprises the steps of: exposing a metal carbide to a heated atmosphere of a first gas to produce a porous carbon material and a metal chloride, the metal carbide containing a first metal and carbon, the first gas containing chlorine gas, and the metal chloride containing the first metal and chlorine; reacting the metal chloride with a second gas in a heated atmosphere to produce a metal oxide and a third gas, the second gas containing oxygen gas, the metal oxide containing the first metal and oxygen, and the third gas containing chlorine gas; and recovering chlorine gas from the third gas, the chlorine gas recovered being used as the chlorine gas for the first gas.
