【摘要】 采用共沉淀法将磁性基质与锌铝水滑石组装制备二维层状磁性锌铝水滑石,考察了不同n(Zn2+)/n(Fe2+)比及焙烧温度对合成磁性锌铝水滑石结构的影响,并借助XRD、FT-IR、VSM、HRTEM等手段对其晶型结构、磁学性能及结晶度等进行表征,结果表明:锌铝水滑石在赋予磁性后,并没有改变其典型的层状结构,证实了将磁性基质与层状材料组装合成的可行性。更多还原

【Abstract】 In this paper,binary layered magnetic Zn-Al hydrotalcite was synthesized with magnetic substrates and Zn-Al hydrotalcite-like compounds by using coprecipitation.The influence of n(Zn²⁺)/n(Al³⁺),n(Zn²⁺)/n(Fe²⁺),and calcination temperatures on the structure were studied.The obtained samples were characterized in detail by HRTEM,XRD,FT-IR,DTA,and VSM.Results indicated that the introduction of magnetic substrates endowed Zn-Al hydrotalcite with magnetism.After that,the typical layer structure still exist,And the feasibility of assembling magnetic substrates with layered material had been approved as well.更多还原
