文摘
- •
Dandelion-like CuO wrapped by rGO nanosheets have been prepared.
- •
The wrapping of rGO contributes to improve the electrochemical performance.
- •
The CuO-rGO electrode exhibits a specific capacitance of 296 F g−1 at 1 A g−1.
- •
The capacitive retention reaches 96.1% after 2000 cycles at 2 A g−1.
