The aromatic compounds used in this study included benzene (99.5%; Shanghai Lingfeng Chemical Reagent Co. Ltd., China),
naphthalene (99%; Sigma-Aldrich),
phenanthrene (98%; Sigma-Aldrich),
1-naphthylamine (98%; Sigma-Aldrich),
2-naphthol (99%; Sigma-Aldrich), chlorobenzene (99.0%; Shanghai Lingfeng Chemical Reagent Co. Ltd.),
o-dichlorobenzene (99%; J&K Chemical, China),
m-dichlorobenzene (97%; Sigma-Aldrich),
p-dichlorobenzene (99.5%; Fluka, Switzerland), 1,2,4-trichlorobenzene (99.0%; Fluka), 1,3,5-trichlorobenzene (99%; Supelco, USA),
p-chlorophenol (99%; Alfa Aesar, USA),
p-chloroaniline (98%; Nanjing Chemical Reagent Co. Ltd., China),
toluene (99.5%; Nanjing Chemical Reagent Co. Ltd),
o-xylene (98.0%; Supelco),
m-xylene (99.5%; Sigma-Aldrich),
p-xylene (99.5%; Sigma-Aldrich),
1,3,5-trimethylbenzene (97%; Macklin, China), nitrobenzene (99.5%; Fluka),
m-dinitrobenzene (97%; Sigma-Aldrich), and 1,3,5-trinitrobenzene (99.9%; Sigma-Aldrich). GO (99.0%) and RGO (98.9%) were purchased from XFNANO Materials Tech (China). GO was prepared by the modified Hammers method (
18 (
link),
23 ) and was mainly in the form of nanosheets with a diameter of 0.5 to 5 μm and thickness of 0.8 to 1.2 nm (according to the information provided by the manufacturer). RGO was prepared by the reduction of GO using
l-ascorbic acid (
48 ). All these materials were used without further purification.
