Fast Formation of SnO₂ Nanoboxes with Enhanced Lithium Storage Capability

Abstract

SnO(2) nanoboxes with uniform morphology, good structural stability, and tunable interior volume can be facilely synthesized by template-engaged coordinating etching of pregrown Cu(2)O nanocubes at room temperature. When evaluated for their lithium storage properties, these SnO(2) nanoboxes manifest improved capacity retention.
