Abstract
A thin nanosheet of mesoporous cobalt carbonate hydroxide (MPCCH) has been fabricated from a CoAl-LDH nanosheet following removal of the Al cations by alkali etching. The basic etched electrode exhibits enhanced specific capacitance (1075 F g(-1) at 5 mA cm(-2)) and higher rate capability and cycling stability (92% maintained after 2000 cycles).
摘要
一种薄的介孔碳酸钴氢氧化物（MPCCH）纳米片已经通过碱刻蚀去除铝阳离子从 CoAl-LDH 纳米片制备得到。基本蚀刻电极表现出增强的比电容（在 5 mA cm(-2) 时为 1075 F g(-1))和更高的倍率性能和循环稳定性（2000 次循环后保持 92%）。
