文摘
A novel complex-assisted hydrothermal route is presented to fabricate ultralong Ag/C nanocables with length rangingfrom 100 to 180 
m on a large scale, based on the reaction of sulfamic acid silver and salicylic acid. By chemicaletching of these Ag/C nanocables, high-quality carbonaceous nanotubes can be obtained at room temperature.Using the as-prepared Ag/C nanocables as templates, a new strategy for introducing guest materials into hollownanotubes is addressed. We take Ag2Se as an example and validate the feasibility of this strategy. All of theproducts are characterized in detail by multiform techniques: X-ray diffraction, Fourier transform IR, energy-dispersiveX-ray analysis, field emission scanning electron microscopy, transmission electron microscopy (TEM), and high-resolution TEM. The formation mechanisms of these products are tentatively proposed.
