Precise tuning of surface composition and electron-transfer properties of graphene oxide films through electroreduction
Graphene materials are generally prepared from the exfoliation of graphite oxide (GO) to graphene oxide, followed by subsequent chemical or thermal reduction. These methods, although efficient in removing most of the oxygen ...
Unusual inherent electrochemistry of graphene oxides prepared using permanganate oxidants
Graphene and graphene oxides are materials of significant interest in electrochemical devices such as supercapacitors, batteries, fuel cells, and sensors. Graphene oxides and reduced graphenes are typically prepared by ...
Carcinogenic organic residual compounds readsorbed on thermally reduced graphene materials are released at low temperature
The preliminary oxidation of graphite to graphite oxide followed by a thermal exfoliation is one of the methods most frequently employed in the preparation of graphene. Such thermally reduced graphene can be widely used ...
Could carbonaceous impurities in reduced graphenes be responsible for some of their extraordinary electrocatalytic activities?
Thermally and chemically reduced graphene materials contain significant amounts of carbonaceous impurities that are similar in structure to amorphous carbon. Herein, we show that the claimed electrocatalytic activities of ...
