Background:　Nanocarbon　hybrids　have　been　a　topic　of　interest　in　recent　years　because　of　their　important　role　in　energy　storage　and　conversion　device　fabrication.　Objective:　To　get　low-cost　Graphene/N-doped　Carbon　Composites　(G-NC)　for　superca-pacitor　applications.　Method:　G-NC　samples　were　prepared　with　a　two-step　hydrothermal　method　and　char-acterized　with　field　emission　scanning　electron　microscopy,　77K　nitrogen　adsorption,　and　X-ray　photoelectron　spectroscopy.　The　electrochemical　performance　of　samples　was　investigated　with　cyclic　voltammetry　and　charge-discharge　measurements　in　three-electrode　configurations.　Results:　Samples　showed　a　sheet-type　morphology　and　nanoporous　structure.　The　na-nohybrids　had　a　specific　surface　area　of　350　m2g-1,　delivered　maximum　specific　capacitance　of　103　F　g-1　at　0.5A　g-1　in　6　M　KOH　with　good　cycle　stability.　Conclusion:　Low-cost　G-NC　nanohybrids　with　good　electrochemical　performance　are　promising　for　supercapacitor　applications.　©　2021　Bentham　Science　Publishers.
