| 摘要 | Creation of three-dimensional (3D) nanostructures is an intriguing method for enhancing the electrochemical properties of energy storage materials. In this study, we have prepared 3D BiVO4/Bi2WO6 (BVO/BWO) flower-like microsphere assembled by 0D BVO nanoparticles and 2D BWO nanosheets via a facile microwave-assisted hydrothermal method. The decoration of BVO nanoparticles onto BWO nanosheets can prevent the BWO nanosheets from restacking in a disorganized manner, thereby facilitating the formation of mesoporous BVO/BWO hierarchical microspheres. Compared with the BVO and BWO single components, the assembled BVO/BWO microspheres show higher surface area, improved electron/ion migration and better structural stability. These characteristics contribute to a rapid and reversible redox process in energy storage applications. The mesoporous BVO/BWO hierarchical microspheres applied for supercapacitor demonstrate a high specific capacitance of 616.8 F/g at 1 A/g and an excellent cycling stability with 87.0 % retention at 4 A/g after 4000 cycles. Additionally, the BVO/BWO composites used as anode materials in lithium ion batteries (LIBs) also deliver a higher capacity of 635.0 mAh/g at 100 mA/g with improved cycling stability compared with the other two samples. |
