Ultrathin corundum-type In2O3 nanotubes derived from orthorhombic InOOH: synthesis and formation mechanism

Single-crystalline metastable corundum-type In2O3 nanotubes were prepared by annealing solvothermally synthesized InOOH nanotubes under ambient pressure at 300 degrees C, and the formation mechanism of the nanotubes was investigated.
