Abstract
We report here a facile strategy to synthesize the nanocomposite
of adenine-modified reduced graphene oxide (AMG) via reaction between
adenine and GOCl which is generated from SOCl<sub>2</sub> reacted
with graphite oxide (GO). The as-synthesized AMG was characterized
by transmission electron microscopy (TEM), atomic force microscopy
(AFM), UV–vis absorption spectroscopy, Fourier transform infrared
(FT-IR) spectroscopy, Raman spectroscopy, thermogravimetric analysis
(TGA), X-ray photoelectron spectroscopy (XPS), cyclic voltammetry
(CV), and galvanostatic discharge analysis. The AMG owns about one
adenine group per 53 carbon atoms on a graphene sheet, which improves
electronic conductivity compared with reduced graphene oxide (RGO).
The AMG displays enhanced supercapacitor performance compared with
RGO accompanying good stability and good cycling behavior in the
supercapacitor
