英文摘要

In this work, dandelion-like NiCo2O4 mesoporous microspheres were uniformly assembled from slim nanowires via a large-scale and templatefree method. The Brunauer-Emmett-Teller (BET) surface area of NiCo2O4 microspheres was determined to be about 35.2 m(2) g(-1) with dominant pore diameter of 10.9 nm and narrow size distribution of 8-20 urn. Furthermore, the electrochemical properties of NiCo2O4 microspheres were evaluated by cycle voltammetric (CV) and galvanostatic charge discharge (GCD) measurements. The results demonstrated that the NiCo2O4 microspheres exhibited high specific capacitance (372 F g(-1) at 1 Ag-1), good rate capability, and excellent cycling stability (88.3% retention after 2000 cycles). In principle, this synthetic approach could be extended for the fabrication of other microstructure materials for promising electrode candidates in energy storage devices.
