Carbon black-intercalated reduced graphene oxide electrode with graphene oxide separator for high-performance supercapacitor
We present a general study on a high performance supercapacitor based on intercalated reduced graphene oxide with carbon black nanoparticles. Graphene oxide sheets were synthesized by oxidation and exfoliation of natural graphite and were reduced using hydroiodic acid in the presence of carbon black nanoparticles. Graphene paper was fabricated by one-step procedure via simultaneous reducing and...
متن کاملReduced Graphene Oxide on Nickel Foam for Supercapacitor Electrodes
The focus of this paper is the investigation of reduced graphene oxide (GO)/nickel foam (RGON) samples for use as supercapacitor electrodes. Nickel foam samples were soaked in a GO suspension and dried before being subjected to two different methods to remove oxygen. Atmospheric pressure annealed (APA) samples were treated with a varying number (10-18) of nitrogen plasma jet scans, where sample...
متن کاملZinc oxide nanoring embedded lacey graphene nanoribbons in symmetric/asymmetric electrochemical capacitive energy storage.
This article describes the synthesis and characterization of ZnO nanoring embedded graphene nanoribbons. Patterned holes (mesopore dia.) in graphene nanoribbons are chemically generated, leading to a high density of the edge planes. These planes carry negatively charged surface groups (like -COOH and -OH) and therefore anchor the metal ions in a cordial fashion forming a string of metal ions al...
متن کاملHIGH PERFORMANCE SUPERCAPACITOR ELECTRODE MATERIAL BASED ON FLOWER LIKE MoS2/REDUCED GRAPHENE OXIDE NANOCOMPOSITE
A simple and cost effective hydrothermal method has been done for the synthesis of MoS2 and MoS2/rGO nanocomposites. The prepared MoS2/rGO composite was characterized by XRD, FESEM and TEM which revealed the formation and as well as the morphological scenario of MoS2/rGO nanocomposite. Pure MoS2 and MoS2/rGO nanocomposite show 3D hierarchical flowery architecture where rGO nanosheets were inter...
متن کاملFacile hydrothermal preparation of graphene oxide nanoribbons from graphene oxide.
Graphene oxide nanoribbons (GONR) with regular edges have been prepared by a facile hydrothermal method. The relatively high yield and convenient preparation of GONR eventually make graphene nanoribbons (GNR) accessible in the field of composite materials where bulk quantities of nanoribbons are required.
