Abstract
In an example of a method, a halogenide-hydrocarbon, an aprotic hydrocarbon solvent, and a reductant are combined to initiate a reaction that forms intermediate particles having a microporous framework. The intermediate particles are subjected to a heat treatment at a heat treatment temperature ranging from about 300° C. to less than 1500° C. for a heat treatment time period ranging from about 20 minutes to about 10 hours to form a precursor to microporous carbon.
Claims18
A method comprising:
- combining a halogenated-hydrocarbon, an aprotic hydrocarbon solvent, and a reductant to initiate a reaction that forms intermediate particles having a microporous framework;
- wherein the aprotic hydrocarbon solvent is selected from the group consisting of toluene, hexane, cyclohexane, and combinations thereof;
- and
- subjecting the intermediate particles to a heat treatment at a heat treatment temperature ranging from about 300° C. to less than 1500° C. for a heat treatment time period ranging from about 20 minutes to about 10 hours to form a microporous carbon.
