Abstract
A activated carbon and a method for manufacturing the same are provided. The activated carbon comprises a carbon aggregate containing a plurality of linear carbons and has a specific surface area of 350 m2/g or more, and the method comprises pretreating a carbon aggregate precursor by ball milling and reacting the pretreated carbon aggregate precursor with CO2.
Claims4
An activated carbon comprising a carbon aggregate containing a plurality of linear carbons and having a specific surface area of 350 m2/g or more,
- wherein cross sections of the linear carbons are exposed on a surface of the carbon aggregate,
- wherein ID/IG of the activated carbon is 2.0 or less, and
- wherein IG is a maximum peak intensity in the range of vibration frequencies from 1560 cm−1 to 1600 cm−1 measured by Raman spectroscopy, and Ip is a maximum peak intensity in the range of vibration frequencies from 1310 cm−1 to 1350 cm−1 measured by Raman spectroscopy.
