Abstract
Graphene is one of the emerging materials in the nanotechnology industry due to its potential applications in diverse areas. We report the fabrication of graphene nanosheets by spontaneous electrochemical reaction using solvated ion intercalation into graphite. The current literature focuses on the fabrication of graphene using lithium metal. Our procedure uses sodium metal, which results in a reduction of costs. Using various characterization techniques, we confirmed the fabrication of graphene nanosheets. We obtained an intensity ratio (ID/IG) of 0.32 using Raman spectroscopy, interlayer spacing of 0.39 nm and our XPS results indicate that our fabricated compound is relatively oxidation free.
Highlights
Graphene nanosheets (GNS) consist of single, bi- or, a few, but fewer than ten, sp2 -hybridized layers of carbon atoms that are in the form of six-membered rings [1,2,3,4]
We present a procedure describing the development of high-quality GNS due to direct contact between graphite powder and Na foil placed within an electrolyte
GNS without steps with sodiation due was to graphite powder This and Na foil being placedvia in direct contact the use of beginning an external energy source investigated
Summary
Graphene nanosheets (GNS) consist of single-, bi- or, a few, but fewer than ten, sp2 -hybridized layers of carbon atoms that are in the form of six-membered rings [1,2,3,4]. Graphitic forms such as 0D fullerene, 1D CNT (Carbon Nano Tubes) and 3D graphite originate from graphene nanosheets [4]. Graphene nanosheets have applications in diverse areas due to their electrical, thermal and mechanical properties [6]. The usage of an ionic liquid complements the properties of graphene for its implementation in energy storage and generation [7]
