graphene oxide nanoribbons and their applications in supercapacitors

we report the enhanced capacitance of the multi-walled carbon nanotubes (mwcnts) after a chemical unzipping process in concentrated sulfuric acid (h2so4) and potassium permanganate (kmno4). the effects of the test duration and temperature were investigated on the unzipping process of the mwcnts to synthesize the graphene oxide nanoribbons. the sem and tem studies were carried out on untreated a...

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 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.

Graphene Oxide Nanoribbons Induce Autophagic Vacuoles in Neuroblastoma Cell Lines

Since graphene nanoparticles are attracting increasing interest in relation to medical applications, it is important to understand their potential effects on humans. In the present study, we prepared graphene oxide (GO) nanoribbons by oxidative unzipping of single-wall carbon nanotubes (SWCNTs) and analyzed their toxicity in two human neuroblastoma cell lines. Neuroblastoma is the most common s...

Graphene oxide nanoribbons exhibit significantly greater toxicity than graphene oxide nanoplatelets.

Graphene oxide (GOs) has emerged in recent years as a versatile nanomaterial, demonstrating tremendous potential for multifunctional biomedical applications. GOs can be prepared by the top-down or bottom-up approach, which leads to a great variability of GOs being produced due to the different procedures and starting carbon sources adopted. This will have an effect on the physiochemical propert...
