Executive Summary : | Supercapacitors (electrochemical capacitors) have elicited extensive research as power supplies to complement or even replace batteries because of their fast recharge capability,high power density, and long cycle life. To improve the energy density while maintaining high power density of electrochemical capacitors for practical applications efforts are being made by many researchers. To improve the performance of Supercapacitors, the research is going on in different ways. One of the ways is testing transition metal ions doped metal sulphide composite as electrodes for Supercapacitors. Metal-Organic Frame Works are evolving as promising electrode materials over other nano structured materials due to their high specific surface area, micro porous structure with interconnections,small ionic radius that makes strong bonding, high coordination number that makes more metal-oxo clusters, and high possibility of reversible redox transitions to make charge storage effectively. The reduced graphene Oxide (rGO) in combination with MOF has the ability to increase bonding interactions and conductivity. The surface interaction between MOF and rGO facilitates catalytic activity and electron transport. CNT-MOFsare also evolving as another challenging materialfor promising electrodes. Plastic waste increasing day-by-day worldwide mainly polyethylene terephthalate (PET) and controlling plastic waste is a challenging task for scientists. The effect of derived MOFs from plastic waste is a promising route to control pollution as well as minimize the cost of MOFs. |
