title: Synthesis of hollow silver nanostructures by a simple strategy.
abstract: Various silver nanostructures with hollow interiors, including nanoscaled cubic or quasi-cubic boxes, tubes, triangular rings, trapeziform rings and hybrid structures composed of tubes and cubic boxes, were synthesized via an extremely simple route. The method involved the modification of the solid silver nanocrystals by dithiol, and subsequent dissolving of the interior metal and assembly of the outer surface. In the whole process, only one simple step of pretreatment was needed before the transformation from Ag solid nanostructures to their corresponding hollow nanostructures. According to the morphological, spectral and structural changes in the evolution from silver solid nanostructures to their corresponding hollow nanostructures, a layer-by-layer assembly mechanism was proposed. The method is believed to open up a simple and versatile route to the fabrication of metallic hollow nanostructures with various morphologies according to the starting templates.
