▎ 摘　　要

NOVELTY - Formation (100) of carbonaceous material involves heating a salt comprising carbon, oxygen, and a metal ion or multiple metal ions at 500-875 degrees C, in the absence of air or oxygen, to drive a chemical reaction to form reaction products comprising the carbonaceous material containing graphene sheets and a carbon templating hexagonal metal oxide. USE - Formation of carbonaceous material used in electrodes of supercapacitors, fuel cells and batteries. ADVANTAGE - The method enhances the formation of graphene sheets and prevents the formation of graphite at low temperatures. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart for the formation of carbonaceous material. Formation of carbonaceous material (100) Production of nitrogen-containing organic salt (105) Pyrolyzing process (110) Solid-liquid separation (115)
