Title: Novel Co{sub 3}O{sub 4} porous polyhedrons derived from metal–organic framework toward high performance for electrochemical energy devices

Abstract

Co{sub 3}O{sub 4} polyhedrons with porous structure have been synthesized simply by annealing Prussian blue analogue (PBA) Co{sub 3}[Co(CN){sub 6}]{sub 2} polyhedrons at 400 °C in air. The product was characterized by a series of techniques, such as X-ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), Transmission Electron Microscopy (TEM), High-resolution TEM (HRTEM), X-ray Photoelectron Spectroscopy (XPS), and Brunauer–Emmett–Teller (BET) gas adsorption. Interestingly, when evaluated as an anode material for lithium-ion batteries (LIBs), the Co{sub 3}O{sub 4} porous polyhedrons manifested high reversible capacity (about 1200 mAh g{sup −1} at 50 mA g{sup −1}) and excellent cycling performance. Moreover, they also exhibited a high specific capacitance of 110 Fg{sup −1} when used as an electrode in the supercapacitor. It is suggested that the special morphology and porous nanostructure lead to the promising electrochemical properties. - Graphical abstract: Novel and complicated mesoporous architectures of Co{sub 3}O{sub 4} have been fabricated by thermal decomposition of Prussian Blue Analog (PBA) Co{sub 3}[Co(CN){sub 6}]{sub 2} polyhedrons which obtained at the room temperature. When Co{sub 3}O{sub 4} product was evaluated for Li-ion batteries (LIBs), they exhibited high reversible capacity of 1000 mAh g{sup −1} with excellent cycle life because of the hollow/porous structure.
