摘　　要：储能材料的性能在很大程度上取决于它们的结构和形貌。我们使用简单的溶剂热方法,通过改变溶剂合成了不同形貌的Ni-1,3,5-苯三甲酸(Ni-BTC)和Ni-1,4-苯二甲酸(Ni-BDC)金属有机骨架材料。Ni-BTC有不规则块状、球状和八面体3种形貌,Ni-BDC有纳米片状、花状和不规则块状3种形貌。对Ni-BTC和Ni-BDC作为超级电容器电极材料的性能进行了研究。结果表明,通过溶剂热方法,在N,N-二甲基甲酰胺(DMF)溶剂中合成出的Ni-BTC和Ni-BDC电极材料的超级电容器性能要优于乙醇(EtOH)和DMF/EtOH(50∶50,V/V)溶剂。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.
