A nanocomposite with the two-dimension (2D) NiO nanoplate of a hexagonal structure and zero-dimension (0D) Co3O4 nanoparticles was synthesized by the hydrothermal method. Scanning electron microscopy, high-resolution transmission electron microscopy, X-ray diffraction and X-ray photoelectron spectroscopy were employed to characterize the composition, morphology, microstructure and chemical state of the nanocomposite, respectively. As an anode material of lithium-ion battery, the nanocomposite exhibits greatly improved specific capacities and stable cyclability of 633 mA h g-1 at a current density of 10 0 mA g-1 up to 70 cycles, much higher than the corresponding building block alone. The outstanding performance of the NiO/Co3O4 nanocomposite is attributed to the hybrid structure and the synergistic effect of different components. This large-scale and cost-efficient synthesis can be extended for the design and synthesis of transition metal oxides composite for high-performance electrochemical energy storage. | | | | | 影响因子: | 4.504 | | | | | 分区情况: | 1区 | | | | | 链接: | http://www.sciencedirect.com/science/article/pii/S0013468615302942 |
