Article Synopsis
- The paper discusses the creation of melamine-based metal-organic frameworks (MOFs) using cheap melamine as an organic linker and cobalt, nickel, and iron as central metal ions for supercapacitor applications.
- It presents techniques to optimize the molecular structures of these MOFs, which were characterized through various methods like X-ray diffraction, electron microscopy, and thermal analysis to confirm their stability and performance.
- The electrochemical tests reveal that the specific capacitance values for Co-Me, Ni-Me, and Fe-Me in a potassium hydroxide electrolyte are significantly high, with Co-Me achieving 1267.36 F/g, indicating their efficiency in energy storage applications.
Mesoporous carbon spheres (MCS-750, MCS-800, MCS-850, MCS-900, and MCS-950) have been synthesized by a facile strategy with low temperature and rapid chemical vapor deposition technique. The synthesized MCS possess relatively large surface area (570-670 m g), good graphitization, remarkable porosity, and redox functionalities on the surface of the synthesized MCS. Combination of these structural and surface properties of the synthesized MCS as an electrode material (MCS-850) showed an excellent charge-storage capacity with a specific capacitance of 338 F/g at 1 mV/s, 217 F/g at 0.
