采用水热法和原位扩散反应法制备了分级纳米片结构的NiMoO 4纳米管。纳米管具有128.5 m（2）g（-1）的高表面积，由高度有序的超薄纳米片组成，厚度小于10 nm。当用作电化学电容器的电极时，该分级纳米管表现出优异的电化学性能。在电流密度为1A·g（-1）时，纳米管的比电容高达864 F·g（-1）。结果表明，基于分级纳米片的NiMoO 4纳米管在储能和其他电化学器件中具有非常有前途的应用。此外，该方法简单易行，可作为一种典型的合成方法推广到其他类型的金属纳米管。
Hierarchical nanosheet-based NiMoO4 nanotubes were synthesized by a hydrothermal treatment and a subsequent in situ diffusion reaction method. The nanotubes with a high surface area of 128.5 m(2) g(-1) were composed of highly ordered ultrathin nanosheets with a thickness of less than 10 nm. When used as electrodes in electrochemical capacitors, the hierarchical nanotubes exhibited excellent electrochemical performances. The specific capacitance of the hierarchical nanotubes was up to 864 F g(-1) at a current density of 1 A g(-1). The results indicate that the hierarchical nanosheet-based NiMoO4 nanotubes are very promising for applications in energy storage and other electrochemical devices. Furthermore, the strategy presented here is facile, and may be expended as a typical method to synthesize other kinds of metal molybdate nanotubes.
