Abstract

Platinum is frequently used as the catalyst in direct methanol fuel cell (DMFC) due to high catalytic activity compared to other catalyst. However, the practical application using platinum is still limited due to high platinum cost. Graphene is the most precious carbon-based material used as the platinum support to reduce the platinum loading which is can reduce the cost. Herein, simple and rapid synthesis of graphene nanosheets (GNs) via chemical reduction of exfoliated graphene oxide nanosheets (GO) was carried out by using sodium oxalate (N a2C2O4) as reducing agent. The comprehensive characterizations were conducted in term of structural and morphology analysis such as Raman spectrometer, high resolution transmission electron microscopy (HRTEM) and x-ray diffractometer (XRD). The number of lay�ers of the GNs was determined by HRTEM which is almost revealed the formation of monolayer. The XRD analysis showed that the large interlayer distance of GO disappeared after reduction process due to the removal of oxygen functional groups to form GNs. Therefore, the reduction process using Na2C2O4 can lead to the ef�ficient removal of the oxygen functional groups from the surface of GO to produce high quality of single layer GNs which is can be applied as the catalyst support in DMFC.
