| 摘要: |
Various compounds with sulfur or diamine structure have been served as ef？cient reducing agents
to convert graphene oxide to reduced graphene oxide. In this work, we used thiourea with both
sulfur and diamine structure to synthesize reduced graphene oxide by the general wet chemical
reduction method. The effective deoxygenation of graphene oxide was con？rmed by Fourier trans-
form infrared spectroscopy, X-ray photoelectron spectroscopy analysis and Raman spectroscopy.
The as-prepared reduced graphene oxide is consisted of few-layered (no more than seven) and
over 60% single-layered graphene sheet determined by atomic force microscopy and transmis-
sion electron microscopy. It also exhibits good dispersion in organic solvents such as ethanol and
N,N-dimethylformamide, which is useful for the further modi？cation of graphene and preparation of
novel nanocomposites. This newly found reducing agent is of low toxicity and nonvolatile, which
makes the reduction much safer. |
