Multiwalled HgX (X = S, Se, Te) Nanotubes Formed with a Mercury Iodide Catalyst in Nanocrystalline Thin Films Spray-Deposited at Low Temperature

X (HgX = S, Se,Te) nanotube formation by low‐temperature spray deposition of solvothermally synthesized HgX nanoparticles is demonstrated. HgI2 is found to act as a catalyst for HgX nanotube growth; the mechanism being similar to that of the catalytic tip growth mechanism of carbon nanotubes. The fi...

Summary:X (HgX = S, Se,Te) nanotube formation by low‐temperature spray deposition of solvothermally synthesized HgX nanoparticles is demonstrated. HgI2 is found to act as a catalyst for HgX nanotube growth; the mechanism being similar to that of the catalytic tip growth mechanism of carbon nanotubes. The figure shows the obtained bamboo‐shaped HgS nanotubes with hexagonal crystal structure and HgSe and HgTe nanotubes with cubic crystal structure (from left to right).
