文摘

ZnCo2O4 nanosheet arrays are grown on Ni foam by hydrothermal route. Effect of precipitating agents on morphology, surface area and porosity of ZnCo2O4. ZnCo2O4 interconnected nanosheets deliver high specific capacitance of 1102 F g−1 ZnCo2O4 bundle-like nanosheets show excellent rate capability. ZnCo2O4 interconnected nanosheets show higher catalytic activity for H2O2 reduction.
