Hausmannite (Mn3O4) is one of the most stable manganese oxides which can be used as an efficient catalyst for oxidative degradation of organic dyes [1]. Graphene oxide / Mn3O4 nanocomposite was synthesized using a reflux method at a temperature of 80 ° C. To identify the structure and morphology, XRD pattern and SEM images of the sample were investigated. The XRD pattern shows the presence of nano sheets of graphene oxide besides the particles of Mn3O4 with a tetragonal crystalline form. The photocatalytic efficiency of the sample was evaluated using a Methyl Orange solution with a concentration of 20ppm. Removal percentage graph of methyl Orange shows the ability of the sample to degrade88.46% of the mentioned dye.
