Two-Dimensional Conductive Metal-Organic Frameworks: Promising Materials for Advanced Energy Storage

With the rapid development of science and technology and for a sustainable future, the main energy resources in the world are transitioning from fossil fuels to renewable electricity which is conceived to play a predominant role in the future. Therefore, it is essential to develop high-performance energy-storage devices such as supercapacitors and rechargeable batteries, and even though they are commercialized, intense research efforts are still devoted to further improving the device performance, e. g. energy density, safety, durability, and charging rate. Therefore, exploring new advanced materials for better devices is a promising approach. Recently, the emerging two-dimensional conductive metal-organic frameworks (2D c-MOFs) with their inherent electrical conductivities and porosity, rich redox active sites, and tailor-made architectures and functions have attracted considerable attention among the energy-storage community. The initial research results revealed that 2D c-MOFs are promising electrode materials for advanced energy storage.
