摘要: 通过对溶剂热"一锅法"合成中碱性溶剂的调整,成功制备了2种形貌不同的Cd(Ⅱ)苯并咪唑基金属有机骨架(Cd-MOF)与氧化石墨烯(GO)的复合材料,利用扫描电子显微镜(SEM)、X射线粉末衍射(XRD)、X射线光电子能谱(XPS)、紫外可见吸收光谱(UV-Vis)和傅里叶红外光谱(FT-IR)对复合材料的结构和性能进行了表征,并研究了其对水中罗丹明B (rhodamine B,RhB)的吸附性能。结果表明:GO的加入增强了Cd-MOF在水中的稳定性,提高了吸附能力;当溶液pH为3.5,吸附时间为60 min时,吸附率可达约95%。 |

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%. |
