Thin single‐crystal tellurium nanobelts and nanotubes have been created by the hydrothermal disproportionation of Na 2 TeO 3 in aqueous ammonia solution, without the presence of any catalysts or templates. It appears that tellurium nanobelts with a helical pitch can be coaxed into chiral nanotubes under these conditions, presenting the promise of a new nanotube synthesis route (see Figure).
