ABSTRACT

In the present study, Fe(II)-based MOF (Fe-BTC, BTC = 1,3,5-benzentricarboxylate) was synthesised via a chemical method and then synthesised hybrid polyorthoaminophenol (POAP)/Fe-BTC films by electropolymerisation of POAP in the presence of Fe-BTC to serve as the active electrode for the electrochemical storage device. The characterisation of Fe-BTC and POAP/ Fe-BTC composite film has been investigated by surface and electrochemical analysis. Benefitting from the intrinsic synergetic contributions from structural/compositional merits, the electrode delivers an impressive capacity of 625 F g⁻¹ at 0.005 mA. This article introduces new nanocomposite materials for electrochemical pseudocapacitor by taking advantage of simple synthesis, high active surface area and stability in an aqueous electrolyte.

摘要

在本研究中，通过化学方法合成了基于 Fe(II) 的 MOF (Fe-BTC, BTC = 1,3,5-benzentricarboxylate)，然后通过 POAP 的电聚合合成了杂化聚邻氨基苯酚 (POAP)/Fe-BTC 薄膜。在 Fe-BTC 存在下用作电化学存储装置的活性电极。通过表面和电化学分析研究了 Fe-BTC 和 POAP/Fe-BTC 复合膜的表征。受益于结构/组成优点的内在协同贡献，该电极在 0.005 mA 时提供了令人印象深刻的 625 F g ^-1容量。本文介绍了用于电化学赝电容器的新型纳米复合材料，该材料具有合成简单、活性表面积大和在水性电解质中稳定的优点。
