Fast Formation of SnO2 Nanoboxes with Enhanced Lithium Storage Capability

Abstract
SnO2 nanoboxes with uniform morphology, good structural stability, and tunable interior volume can be facilely synthesized by template-engaged coordinating etching of pregrown Cu2O nanocubes at room temperature. When evaluated for their lithium storage properties, these SnO2 nanoboxes manifest improved capacity retention.
