The magnesium di-oxide (MgO2) nanorods were synthesized by using graphene oxide (GO) as catalyst by simple and efficient chemical reaction method. Graphene oxide acts as a catalyzer for the formation of nanorods. The amounts of magnesium (Mg) powder were varied such as 200 mg, 400 mg and 600 mg. The formation of nanorods was increases as increasing the amount of magnesium powder. Prepared magnesium oxide found in two different phases, such as MgO2 (cubic phase) and MgO4 (hexagonal phase). Also (001) peak of graphene oxide were reduced completely and intensity of magnesium oxide peaks were increased. But existence of graphene oxide was confirmed by Raman spectroscopy which concludes the formation of graphene oxide/magnesium oxide (GO/MO) composite. The investigation of the different functional groups was carried by FTIR study. The increase in the formation of nanorods with increasing the magnesium metal was confirmed by EDS and FESEM results.
