| Solvent-Controlled Morphology of Ni-BTC and Ni-BDC Metal-Organic Frameworks for Supercapacitors | |
| 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。 | |

| Abstract: 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. | |
