Synthesis of nanoporous carbon derived from hybrid metal organic frameworks for symmetric supercapacitor

Metal-organic frameworks (MOFs) have received much interest due to their remarkable properties, such as high surface area, controllable porosity, high electrical conductivity, high thermal stability, and good chemical stability. In addition, the properties of a MOF could be tuned by incorporation with other compounds. More interestingly, their structure could be transformed into nanoporous carbon materials via the carbonization process. Nanoporous carbons (NPCs) are promising electrode materials for electrical energy storage (i.e., batteries and supercapacitors) due to their unique properties, such as good thermal and chemical stability, high surface area, and tunable pore structures. Nowadays, the development of new electrode materials that yield high performance is essential to overcome their current issues - for instance, low energy density, low voltage per cell, and high selfdischarge. Nanoporous carbons derived from hybrid zeolitic imidazolate frameworks (ZIFs) can provide promising potentials in high-performance supercapacitor by combining two different metal ions, Zn2+ and Co2+, followed by KOH activation. The main objective of this work was to synthesize, characterize, and evaluate nanoporous carbons (NPCs) and activated carbons (ACs) derived from bimetallic ZIFs. This study also investigates the electrochemical behaviour of the obtained materials.
