Abstract

A facile one-step sacrificial templating solution route for the large-scale synthesis of a new kind of long Ag2SiO3/SiO2 composite nanotube has been achieved using silver molybdate nanowires (see Figure, left) as a sacrificial template at ambient temperature. In-situ embedding of Ag2SiO3 nanoparticles on the backbone (see Figure, right) is demonstrated, and seems a promising strategy in order to endow the silica nanotubes with new properties.
