Abstract
This disclosure relates to porous carbon and a method of preparing the same. The porous carbon of the present invention is derived from a carbonitride compound having a composition comprising metal and nitrogen. The porous carbon of the present invention comprises both micropores and mesopores, and has a large specific surface area, and thus, may be usefully used in various fields.
Claims12
A method for preparing porous carbon comprising the steps of:
- mixing at least one metal source selected the group consisting of metals selected from Ti, V, Cr, Zr, Nb, Mo, W, Hf, and Ta, and oxides thereof with a carbon source;
- heating the mixture under nitrogen atmosphere to form a carbonitride compound;
- reacting the carbonitride compound with halogen gas;
- and
- heating the reaction mixture under hydrogen atmosphere.
