Abstract
In this research, three-dimensional graphene (3DG) was synthesized via thermal CVD method by using
nickel foam in a tube furnace. This method consists of graphene growth on the nickel foam using Ar and H2 gases and
ethanol carbon precursor, followed by removal of nickel foam by chemical etching. Finally, the synthesized graphene
was characterized by XRD, SEM and Raman analyses. The electrical conductivity and work function of 3DG were
determined by Van der Pauw method and UPS technique, respectively. The results indicated that the high porosity and
good quality three-dimensional graphene was formed. The electrical conductivity and work function of 3DG were
measured 4 s.cm-1 and 5 eV, respectively.
