摘　　要：无机-有机杂化材料因其具有多孔结构和易实现不饱和配位的特点在吸附领域广泛应用,其作为吸附剂用于染料废水的处理非常有前景。本文采用溶剂热法合成了一例结构新颖的锌基无机-有机杂化材料(Zn-BTC)。结构解析表明该材料属于立方晶系,具有■空间群,由典型的四连接桨轮双核锌和三连接双核锌单元构成高对称的无机-有机杂化材料。研究了该材料对有机染料茜素红和亚甲基蓝的吸附性能。结果表明:Zn-BTC在11 h内对茜素红吸附量达到7.53 mg/g,对亚甲基蓝吸附量达到4.20 mg/g。通过X射线光电子能谱仪(XPS)、扫描电子显微镜(SEM)和透射电子显微镜(TEM)等技术手段对吸附前后的Zn-BTC进行表征,证明该材料具有良好的稳定性和优异的吸附性能。Inorganic-organic hybrid materials are widely used in the field of adsorption because of their porous structure and easy realization of unsaturated coordination.They are very promising as adsorbents for the treatment of dye wastewater.In this study,a Zn-based inorganic-organic hybrid material(Zn-BTC) with novel structure was synthesized by solvothermal method.The structural analysis indicated that the material belonged to the cubic crystal system with Pm3m space group.A highly symmetric binuclear metal-based porous three-dimensional framework was formed by a typical quadruple paddle wheel and cationic triple-connected binuclear zinc units.The adsorption properties of the material for the organic dyes including alizarin red and methylene blue were investigated.The results showed that the adsorption capacity of alizarin red and methylene blue by Zn-BTC reached 7.53 mg/g and 4.20 mg/g within 11 h.Zn-BTC before and after adsorption was characterized by means of X-ray photoelectron spectroscopy(XPS),scanning electron microscope(SEM) and transmission electron microscopy(TEM).The results demonstrated that the material exhibited good stability and excellent adsorption properties.
