The facile ionic liquid-assisted synthesis of hollow and porous platinum nanotubes with enhanced catalytic performances

A facile one-pot synthetic method was developed to synthesize hollow and porous Pt nanotubes (Pt-HPNTs) using silica nanorods as a template, ionic liquid as a precipitator and reductant, and in situ generated KCl as an etching agent. The work reported here might open a new route for the synthesis of hollow nanostructures.
