A new nanostructure, a “nano-box-beam”, of tin dioxide has been synthesized using a vapor deposition process in open atmosphere (see Figure). Each as-grown SnO2 nanotube is a single crystal with four {110} peripheral surfaces and [001] growth direction. The new nanostructure could be used in devices such as nanobatteries, nanoscale fuel cells, and nanosensors.
