Abstract
The development of a reliable platform for the electrochemical characterization of a redox-active molecular diiron complex, [FeFe], immobilized in a non-conducting metal organic framework (MOF), UiO-66, based on glassy-carbon electrodes is reported. Voltammetric data with appreciable current responses can be obtained by the use of multiwalled carbon nanotubes (MWCNT) or mesoporous carbon (CB) additives that function as conductive scaffolds to interface the MOF crystals in "three-dimensional" electrodes. In the investigated UiO-66-[FeFe] sample, the low abundance of [FeFe] in the MOF and the intrinsic insulating properties of UiO-66 prevent charge transport through the framework, and consequently, only [FeFe] units that are in direct physical contact with the electrode material are electrochemically addressable.
摘要
本文报道了一种基于玻碳电极，用于固定在非导电金属有机框架（MOF）UiO-66中的氧化还原活性分子双铁配合物[FeFe]进行电化学表征的可靠平台的开发。通过使用多壁碳纳米管（MWCNT）或介孔碳（CB）添加剂作为导电支架，在“三维”电极中连接MOF晶体，可以获得具有明显电流响应的伏安数据。在所研究的UiO-66-[FeFe]样品中，MOF中[FeFe]的低丰度以及UiO-66的固有绝缘特性阻碍了电荷通过框架传输，因此，只有与电极材料直接物理接触的[FeFe]单元才能进行电化学寻址。
