Synthesis of shape-controlled β-In2S3 nanotubes through oriented attachment of nanoparticles

β-In2S3 nanotubes were synthesized using an organic solution pyrolysis route. The shape of the β-In2S3 nanotubes was controlled from hexagonal nanoplates to nanotubes simply by changing the reaction time. The growth mechanism of the nanotubes was explained by oriented attachment. The β-In2S3 nanotubes had a diameter, wall thickness and length of 5.0 nm, 0.79 nm and >10 μm, respectively. The diameter of the β-In2S3 nanotubes was found to be dependent on the sulfur concentration.
