摘要：

Porous single-crystalline nanosheet (NS) arrays of Co3S4 have been synthesized via a simple shape and phase transformation route, which exhibits high specific capacitance (1081 F g(-1) at 1.61 A g(-1)) and areal capacitance (2.69 F cm(-2) at 4 mA cm(-2) and 2.33 F cm(-2) at 12 mA cm(-2)) with good cycling performance (96.2% capacitance retention after 3000 cycles).
