Probing the effect of solvents on the electrochemical performance of graphene incorporated nickel-based metal organic frameworks

Highly porous coordinated metal-organic frameworks (MOFs) have attracted enormous interest by virtue of their promising electrochemical performance in the application of energy storage systems. In this study, the associated electrochemical performance of nickel-based MOFs (Ni-3(OH)(2)(C8H4O4)2(H2O)(...

description Highly porous coordinated metal-organic frameworks (MOFs) have attracted enormous interest by virtue of their promising electrochemical performance in the application of energy storage systems. In this study, the associated electrochemical performance of nickel-based MOFs (Ni-3(OH)(2)(C8H4O4)2(H2O)(4)]center dot 2H(2)O, Ni-MOFs) synthesized in different solvent systems was systematically investigated. It is found that binary solvents with high polarity and viscosity were favorable for the formation of small-sized nanosheets.
