Reduced Graphene Oxide-Cr2O3 Nanocomposite as Electrode Material in Supercapacitors

In recent years, electrochemical supercapacitors have received considerable attention from many researchers. Metal oxides such as chromium oxide with high redox activity, high specific capacity, and excellent reversibility are suitable alternatives to ruthenium oxide in supercapacitor applications. In this study, first, graphene oxide (GO) was synthesized by the modified Hummers method. The syn...

Facile Synthesis of MnPO4H2O Nanowire/Graphene Oxide Composite Material and Its Application as Electrode Material for High Performance Supercapacitors

In this work, we reported a facile one-pot hydrothermal method to synthesize MnPO4·H2O nanowire/graphene oxide composite material with coated graphene oxide. Transmission electron microscopy and scanning electron microscope were employed to study its morphology information, and X-ray diffraction was used to study the phase and structure of the material. Additionally, X-ray photoelectron spectro...

Graphene-based nanowire supercapacitors.

We present a new type of electrochemical supercapacitors based on graphene nanowires. Graphene oxide (GO)/polypyrrole (PPy) nanowires are prepared via electrodepostion of GO/PPy composite into a micoroporous Al2O3 template, followed by the removal of template. PPy is electrochemically doped by oxygen-containing functional groups of the GO to enhance the charging/discharging rates of the superca...
