通过不同的还原处理和性能比较，合理设计了一组相同但氧空位量不同的Co 3 O 4纳米片。值得注意的是，富氧空位Co 3 O 4纳米片（OVR-Co 3 O 4 NS）表现出优异的电化学性能，作为下一代超级电容器的潜在候选者。
A set of identical Co3O4 nanosheets with different oxygen vacancy amounts are rationally designed by varied reduction treatments and comparison of their properties. Remarkably, the oxygen-vacancy-rich Co3O4 nanosheets (OVR-Co3O4 NSs) exhibit excellent electrochemical performance for their potential use as a promising candidate for the next generation of supercapacitors.
