Effect of Various Amounts of Hydrazine and Graphene Oxide on the Photocatalytic Performances of the ZnSe/Graphene Nanocomposites

Abstract:

In this study, the hydrothermal method was used for synthesizing ZnSe/graphene nanocomposites with the amount of graphene oxide (GO) and hydrazine. Obtained ZnSe/graphene photocatalysts were characterized by X-ray diffraction analysis (XRD) and transmission electron microscope (TEM). Photocatalytic activity under visible light is evaluated in methylene blue (MB) dye degradation reaction in aqueous phase. The results show that the amount of graphene oxide (GO) and hydrazine have an effect on the degradation efficiency of the ZnSe/graphene nanocomposite. When GO/ZnSe ratio was 1. The optimum degradation efficiency of the ZnSe/graphene nanocomposites prepared with 5 mL of N₂H₄ was 99.6% after 5h of visible light irradiation.
