1. A method of producing reduced graphene oxide, comprising:
thermally processing an amount of coal to achieve a predetermined concentration of an one or more impurity atoms in the amount of coal;
oxidizing at least some of the amount of coal to form a coal oxide including a predetermined concentration of the one or more impurity atoms;
processing the coal oxide to form reduced graphene oxide including a predetermined concentration between about 0.1 atomic % and about 10 atomic % of the one or more impurity atoms.
