Tailoring the hollow structure within CoSn(OH)6 nanocubes for advanced supercapacitors
View through CrossRef
Abstract
Hollow structure is benefited for various application of the materials owing to it makes the materials the large surface area with more active sites. In this work, hollow structure was engineered into dense CoSn(OH)6 nanocube precursors by alkaline etching, resulting in both increased surface area and mesopores with large size. Hollow CoSn(OH)6 nanocubes as the active component of the cathode electrode exhibited a highly electrochemical capacitance of 1.136 mAh cm-2 at 2 mA cm-2 , larger than that of corresponding dense precursor. Meanwhile, good rate capability for hollow CoSn(OH)6 nanocubes was achieved by increasing 4-fold current density. Considering its facile fabrication and highly electrochemical performance, the obtained CoSn(OH)6 nanocubes are a promising material for use in energy storage.
