| Abstract: In this work, two different morphologies of composites with Cd (Ⅱ) benzimidazole-derived metal-organic framework (MOF) and graphene oxide (GO) were successfully synthesized by adjusting the alkali environments in the one-pot solvothermal process. The structures and properties of these composites were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), UV-visible absorption spectra (UV-Vis), and FT-IR. The adsorption performance of these composites for rhodamine B (RhB) in water was studied. The results showed that GO and Cd-MOF were successfully combined, and the addition of GO enhanced the stability of Cd-MOF in water and improved its adsorption capacity. When the pH value of the solution was 3.5 and the adsorption time was 60 min, the adsorption rate could reach ca. 95%. |
