Graphene is a two dimensional material which carbon atoms arranged in hexagonal lattice in itwith very strong covalent bond and because of its very specific mechanical, electrical and thermalproperties and also low density and vary large surface area attracted many researchers in lastdecade. In this research graphene oxide (GO) was synthesized by simple Hummer‟s method andreduced with sodium borohydride (NaBH۴) and oxalic acid and their properties were compared.For characterization of samples X-ray diffraction, Raman spectroscopy, FT-IR spectroscopy,UV-vis spectroscopy and TG analysis were used. The results showed that the quality of reducedgraphene oxide with NaBH۴ (rGO-NaBH۴) is better than reduced graphene oxide with oxalic acid(rGO-oxalic acid).
