Abstract
The disclosure provides for methods of oxidizing carbide anions, or negative ions, from salt like carbides at low temperatures below about 600° C. In another aspect, the disclosure provides for reactions with intermediate transition metal carbides. In yet another aspect, the disclosure provides for a system of reactions where salt-like carbide anions and intermediate carbide anions are oxidized to produce pure carbon of various allotropes.
Claims19
A method comprising:
- reacting a carbide chemical compound with a metal salt at a reaction temperature of below 600° C. to form reaction products comprising carbon and elemental metal,
- wherein the reaction comprises an oxidation of the carbide chemical compound and a reduction of the metal salt and
- wherein a hybridization type of the carbon is controlled by changing a species of a cation of the metal salt, by changing the reaction temperature, and/or by changing a species of the metal salt and thereby changing a melting temperature of the metal salt.
