沸石咪唑酯骨架结构材料的合成及其复合物在微波吸收和超级电容器中的应用

发布时间：2021-02-02 13:31

　　与常规材料相比,沸石咪唑酯骨架结构材料（ZIFs）可以说是一类新型的金属有机骨架,它含有咪唑化物连接基和金属离子以及类似铝硅酸盐沸石的结构。多年来,越来越多的人对ZIF产生了兴趣,其固有的多孔特性以及出色的化学性质和可控的结构特征导致在气体吸附,分子传感,能量存储设备,光电,催化,生物医学,药物负载,磁性能以及电磁屏蔽和隐身技术等领域得到了广泛的应用。此外,ZIF基材料可作为出色的模板,用于生产多孔碳和相关的纳米结构复合材料,这些复合材料具有较大的表面积,均匀的孔,平衡的金属/有机比以及相对于其骨架而言可控的结构。近年来,人们在这一快速发展领域中专注于先进的合成方法以及有吸引力的应用研究。本文主要研究ZIFs的制备,纳米结构复合材料以及ZIFs的应用。研究了 ZIFs的合成方法,形貌,结构性质,详细讨论了磁性,声子限制,超级电容,电子极化,电磁波吸收和屏蔽。本文的研究部分主要包括以下五个方面:（1）异质结构的TiO2/C/Co纳米材料是由碳化的沸石咪唑酸盐（ZIF-67）多孔骨架衍生而来,获得了包覆有TiO2的均匀纳米球结构,显示出了优异的微波吸收性能。迄今为止,在传统层面尚未在文献中...
