Abstract
Powdered, amorphous carbon nanomaterials are formed from a carbon precursor in reverse microemulsion that includes organic solvent, surfactant and water. Methods for manufacturing amorphous, powdered carbon nanomaterials generally include steps of (1) forming a reverse microemulsion including at least one non-polar solvent, at least one surfactant, and at least one polar solvent, (2) adding at least one carbon precursor substance to the reverse microemulsion, (3) reacting the at least one carbon precursor substance so as to form an intermediate carbon nanomaterial, (4) separating the intermediate amorphous carbon nanomaterial from the reverse microemulsion, and (5) heating the intermediate amorphous carbon nanomaterial for a period of time so as to yield an amorphous, powdered carbon nanomaterial. Amorphous, powdered carbon nanomaterials manufactured according to the present disclosure typically have a surface area of at least 500 m/g, a graphitic content of at least 25%, and a conductivity of at least 150 S/m.
