The　effect　of　treatment　on　the　de-oxygenation　and　restoration　of　π-　π　conjugation　of　graphene　oxides　(GO),　through　basic　(sodium　hydroxide　(NaOH),　sodium　borohydride　(NaBH4),　hydrazine　hydrate,　and　NaBH4　and　hydrazine　hydrate)　and　neutral　(superheated　H2O)　reducing　agents　has　been　studied.　Reduced　GO　samples　were　extensively　characterized　by　Raman　spectroscopy,　X-ray　photoelectron　spectroscopy,　transmission　electron　microscopy,　elemental　analysis,　thermogravimetric　analysis,　and　electrical　conductivity　measurements.　It　was　found　that　treatment　with　hydrazine　hydrate　was　the　most　effective　for　the　reduction　of　GO.　NaBH4　and　superheated　H2O　were　the　next　best　performing　reducing　agents,　and　NaOH　was　the　least　efficient.　This　study　demonstrates　that　by　varying　the　reducing　agent,　one　can　modify　the　physical　and　chemical　properties　of　reduced　GO,　including　electrical　conductivity　and　thermal　stability.　Copyright　©　2013　American　Scientific　Publishers　All　rights　reserved.
