Claims15
A method of manufacturing an activated carbon, the method comprising:
- preparing a carbon precursor;
- carbonizing the carbon precursor by heat treating thereon;
- equalizing the carbon precursor carbonized by grinding them;
- and
- activating the equalized carbon precursor by adding an oxidizing agent and distilled water into the equalized carbon precursor and heat treating thereon, to form the activated carbon,
- wherein a volume of the oxidizing agent is in a range of about 10 volume % to 50 volume % for a total of 100 volume % of the oxidizing agent and the distilled water, in the activating,
- wherein the oxidizing agent includes H2O2, and wherein the activating is performed at a temperature in a range of about 700° C. to 1000° C.
