Abstract

The development of an easy fabrication method for highly ordered tetragonal single-crystal SnO₂ nanowire arrays using anodic alumina membrane (AAM) as a template through a sol-gel route employing citric acid as a chelating complex was reported. The image of a single SnO₂ nanowire and the corresponding selected area electron diffraction (SAED) pattern indicates the typical characteristics of a perfect single-crystal structure where all the diffraction spots can be indexed to the zone axis of SnO₂. The results show that citric acid partially coordinates with the hydrozyl groups on the walls of AAM pores forming Sn-citric acid-AAM bonds. The SnO₂ nanowire array exhibits a reversible capacity of 418 mA h/g based on the weight of SnO₂ in the first cycle.
