| مستخلص: |
Porous NiO architecture has been successfully prepared by calcining a novel Ni-MOF in air. As revealed by XRD, SEM and TEM, the obtained NiO architecture is assembled from two-dimensional nanosheets, which primarily consist of uniform nanoparticles and large quantities of pores between nanoparticles. Electrochemical data present that the NiO architecture possesses a reversible specific capacitance of 324 F g −1 after 1000 cycles at 1 A g −1 , and nearly 46% capacity retention when the current density increases from 1 to 40 A g −1 , suggesting its promising application in supercapacitors.
