Synthesis of reduced graphene oxide by using palm oil mill effluent (POME)

The increase of world palm oil demand has driven a significant increase in palm oil production. Indirectly, palm oil mill effluent (POME) production also has increased drastically. In the material science field, graphene is a marvellous material due to its high specific surface area (theoretically 2...
