- Abstract
A new type of electrode has been prepared by composite of molybdenum disulfide (MoS2) and graphene oxide (GO), and applied in adsorbing Pb(II) in water using capacitance deionization method. The electrode was characterized by X⁃Ray Diffraction (XRD), Raman, Transmission Electron Microscopy(TEM), and Brunauer⁃Emmett⁃Teller(BET). The adsorption mechanism was investigated using X⁃ray photoelectron spectroscopy (XPS), XRD and cyclic voltammetry (CV). The results indicate that GO in the GO/MoS2 composite could prevent aggregation of MoS2 and increase the interface of electrode with electrolyte. Besides, the absorption mechanism is proved to be the synergistic absorption effects of double electrode layer and pseudo⁃capacitance, and the former is more effective. The adsorption capacity of GO/MoS2 composite electrode is 4 614.9 mg/g, higher than that of pure GO 1 876.9 mg/g and pure MoS2 1 175.4 mg/g, Therefore, GO/MoS2 electrode shows superior performance in removal of Pb(II) with high concentration.
