Preparation, characterization and photocatalytic properties of reduced graphene oxid- zinc oxide hybrid nanocomposites by green synthesis

RGO/ZnO is nanocomposite (NC) hybrid based on graphene as a new generation of nanotechnology compounds that due to significant and suitable properties in various fields such as industry and medicine has been widely used as a photocatalyst and biomarker [1, 2]. Developing of new methods for the synthesis of nanomaterials caused concerns about environmental pollution and dangerous lateral products in the field of industry and medicine. As a result, the methods that prevented of chemical substances in NC structure is important. Phytosynthesis methods including advantages such as environment-friendly, low cost and cheap primary materials. In this research, for the first time, ZnO @GO hybrid NC were obtained by reduction method of Zn2+ and GO by using fruit extract of Rosa canina. In this paper, RGO/ZnO NC synthesized by extract rosa cannina and the photocatalytic activities were evaluated by degradation of methylorange (MO) aqueous solution under visible light (9 W LED lamp) irradiation [3]. The composites of Graphene oxid (GO)/zinc oxide (ZnO) nanoparticles (NPs) with different GO wt %, (4%, 8%, 12%, 16% and 20%), were synthesized by an in Green Synthesis method. The synthesized NP were characterized by SEM and XRD, DLS, zeta potential techniques. The degradation efficiency of methyl orange (MO) in the presence of ZnO-doped GO was higher than that of prior ZnO. Various parameters affecting the degradation efficiency such as amount of percent dopant, oxidant concentration, degradation time and Methyl Orange (MO) concentration. This work open window for degradation of oil-based pollutants in the field of petroleum and gas technologies [4]. Our work in this area is ongoing.
