Facile Synthesis of Porous Zn–Sn–O Nanocubes and Their Electrochemical Performances

Porous Zn–Sn–O nanocubes with a uniform size were synthesized through a facile aqueous solution route combined with subsequent thermal treatment. The chemical composition, morphology, and microstructure of Zn–Sn–O nanocubes, which have significant effects on the lithium storage performances, were easily tuned by adjusting the calcination temperature in preparation processes of ZnSn(OH)6solid nanocubes. Further studies revealed that porous Zn–Sn–O nanocubes prepared at 600 °C exhibited a good rate capability and a high reversible capacity of 700 m Ah g-1at a current density of 200 m Ag-1after 50 cycles, which may be a great potential as anode materials in Lithium-ion batteries.
