摘要

应用金属有机配合物作前驱体,煅烧制备有稳定结构的介孔NiO电极.TEM孔径分布及电化学测试表明,该电极结构规整,平均孔径为30 nm.在2.0 A·g-1电流密度下,比电容为72 F·g-1.1000次循环后,几乎无衰减,而且其表面介孔结构相当稳定.

Abstract

Mesoporous nickel oxide has been synthesized by calcining metal-organic coordination precursor.Transmission electron microscopy and BET test showed that the prepared NiO had a regular morphology and displayed a narrow size distribution.Electrochemical tests revealed that such mesoporous NiO had a specific capacity of 72 F·g-1 at the current of 2.0 A·g-1.Futhermore,the material showed excellent cycle-life stability.There was no degradation of capacitance after 1000 cycles.

Key words： supercapacitor; mesoporous nickel oxide; cycle-life stability
