以煤- ldh纳米片为原料，采用碱刻蚀法去除Al阳离子，制备了介孔碳酸钴氢氧化物（MPCCH）纳米片。基本蚀刻电极表现出增强的比电容（在5 mA cm（-2）时1075 F g(-1)）和更高的倍率能力和循环稳定性（在2000次循环后保持92%）。
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).
