文摘
- •
NiO nanoparticles are encapsulated in mesoporous carbon nanospheres (MCNs).
- •
The reaction of silicate-ion groups with Ni2+ ions is utilized to in situ introduce NiO.
- •
NiO/MCNs have regular geometry, uniform diameter and mesopore, and high surface area.
- •
NiO/MCN electrode exhibits high specific capacitance and excellent cycle stability.
