Potassium assisted reduction and doping of graphene oxides: towards faster electron transfer kinetics
Original language description
The current scientific interest and fervour in graphene research is fuelled by their potential uses in a variety of fields such as energy storage, electrochemical and biomolecule sensing applications. In particular, many of these require the bulk production of graphene materials, using approaches such as the oxidation of graphite to graphite oxide with chlorate or manganate oxidants in the presence of strong acids. This is followed by its reduction via thermal exfoliation, or through chemical and electrochemical reduction methods. Elemental potassium is a very strong reducing agent with a chemical potential of ca. E = -2.93 V versus the standard hydrogen electrode. Therefore, in this paper we evaluate the effects of the presence of elemental potassiumas a strong reductant during the thermal exfoliation of graphite oxides. We employ both the Hofmann and Hummers methods of graphite oxidation, followed by their thermal reduction at 500 degrees C both in the absence and presence of elemen
