Nickel cobalt oxide nanowire-reduced graphite oxide composite material and its application for high performance supercapacitor electrode material
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 unifor...

| description | 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 NiCo2O4 nanowire 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−1 at 0.5 A g−1 and 512 F g−1 at 40 A g−1. This method provides a promising approach towards low cost and large scale production of supercapacitor electrode material. |
