Abstract

In this paper, we report a facile synthesis method of mesoporous nickel cobalt oxide (NiCo₂O₄) nanowire-reduced graphite oxide (rGO) composite material by urea induced hydrolysis reaction, followed by sintering at 300 ^°C. P123 was used to stabilize the GO during synthesis, which resulted in a uniform coating of NiCo₂_O₄nanowire on rGO sheet. The growth mechanism of the composite material is discussed in detail. The NiCo₂O₄-rGO composite material showed an outstanding electrochemical performance of 873 F g^-1at 0.5 A g^-1and 512 F g^-1at 40 A g^-1. This method provides a promising approach towards low cost and large scale production of supercapacitor electrode material.
