Transition-Metal-Based Zeolite Imidazolate Framework Nanofibers via an Electrospinning Approach: A Review

Zeolite imidazolate frameworks (ZIFs) are a subclass of metal organic frameworks (MOFs) and have been considered as a special finding in the current platform of the research arena. ZIFs have been comprised of metal ions with imidazolate linkers. In recent times, ZIFs have been predominately utilized for various applications. This excellent feature is because of its fascinating properties. During the evolution of the materials era, one-dimensional (1-D) fibrous materials are also considered as an important area of research. In order to make the fibrous materials, electrospinning (ES) is considered as a more reliable way for their synthesis. 1-D material has also been utilized for various applications owing to their abnormal physicochemical properties. In this mini-review, the recent developments with various processes have been followed for the synthesis of ZIF materials and 1-D fibrous materials. We elaborated their advantages over their applications in the past years which are discussed and reviewed. More importantly, we have proposed a new area for the incorporation of transition-metal-based ZIF materials into the 1-D fibrous materials, which confers the new direction to the research community to explore its use in various applications.
