摘要
锌、镍和铝物质的量比为1∶3∶2,以尿素为沉淀剂,采用均相沉淀技术制备Zn^(2+)-Ni^(2+)-Al^(3+)-CO_3^(2-)-LDHs。以Zn^(2+)-Ni^(2+)-Al^(3+)-CO_3^(2-)-LDHs为前驱体,分别与Cl-和MnO_4^-进行离子交换,将MnO_4^-引入Zn^(2+)-Ni^(2+)-Al^(3+)-LDHs层间制备Zn^(2+)-Ni^(2+)-Al^(3+)-MnO_4^--LDHs新型复合材料。通过XRD、SEM、FT-IR和EDS等对合成产物Zn^(2+)-Ni^(2+)-Al^(3+)-MnO_4^--LDHs进行表征。结果表明,Zn^(2+)-Ni^(2+)-Al^(3+)-MnO_4^--LDHs复合材料结晶度较高,层间距为0.912 nm,具有明显的六边形层状结构,片层横向尺寸约为3μm,厚度约为100 nm。
Zn^2+-Ni^2+-Al^3+-MnO4^-LDHs was prepared by homogeneous precipitation using urea as precipitator and molar ratio of zinc: nickel : alumina = 1: 3:2. Zn^2+ - Ni^2+ - A1^3+ - MnO4^-- LDHs was compounded though ion exchange with C1^- and MnO4_ respectively using Ni^2+ - A1^3+ - CO3^2- - LDHs as precursor and characterized by XRD,SEM,FT-IR and EDS. Results showed that Zn^2+ - Ni^2+ - A1^3+ - MnO4^- - LDHs exhibited hexagonal layered moqohology and interlayer space was 0. 912 nm. Plane size of synthetic products was 3 μm and thickness was about 100 nm.
