Anotācija Graphene oxide (GO) reduction is a promising way for graphene l arge scale synthesis. Pre-exfoliated graphite was oxidized and reduced. The material w as compared to commercial graphene oxide and its reduced sample. The reduction process of grap hene oxide is accomplished using sodium borohydride (NaBH 4 ) with variable-valence metal ion – cobalt – assistance. The reduced graphene oxide (RGO) was characterized by Raman sp ectroscopy. The particle size and suspension stability were determined. Electrical conductivity me asurements of GO and RGO samples have been done in temperature range from -150°C to 85°C. Pre -exfoliation effect was determined.
