1. 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.
