  • The performance of energy storage materials is substantially dependent on their nanostructures. Herein, Ni-1, 3, 5-benzenetricarboxylate (Ni-BTC) and Ni-1, 4-benzoate (Ni-BDC) metal-organic frameworks with different morphologies were controllably synthesized using a facile solvothermal method by simply adjusting the solvent, including Ni-BTC blocks, nanospheres, and double-pyramid structures and Ni-BDC nanosheets, nanoflowers and blocks structures, and their electrochemical performance as supercapacitors was thoroughly investigated. Moreover, our study showed that the supercapacitor performance of the electrode materials obtained for Ni-BTC and Ni-BDC electrodes in pure N, N-dimethylformamide (DMF) solvent was better than those prepared with pure ethanol (EtOH) and DMF/EtOH (50:50, V/V) as solvent.
