摘要：
The pure NiMoO4 and sphere-shaped NiMoO4@rGO nanostructure were obtained by one step hydrothermal process. The sphere-shaped NiMoO4@rGO nanostructure showed higher significantly specific capacitance value than pure NiMoO4. The enhanced capacitive performance of the as-prepared sphere-shaped NiMoO4@rGO nanostructure was attributed to the mesoporous structure, large surface area of rGO nanosheets and higher electrical conductivity. These mesoporous structures could provide more electroactive sites which promoted the electrode-electrolyte contact and enhanced ion and electron transport during the chemical reaction. Moreover, high specific capacitance also could be attributed to the positive synergistic effect between rGO and NiMoO4. (C) 2017 Elsevier B.V. All rights reserved.
