“…Therefore, 1D nanostructures of silver have attracted increasing interest due to their potential applications as building blocks for nanoscale electronic, optoelectronic, and magnetic devices. So far, many 1D silver nanostructures (such as nanowires, nanorods, and nanotubes) have been successfully prepared by means of different synthetic strategies including surfactant-assisted synthesis [1][2][3][4], hard template-directed methods [5][6][7][8][9][10], surfactantless methods [11,12], and electrochemical deposition methods [13,14]. Recently, many efforts have been devoted into the synthesis of a special 1D silver co-axial heterostructures (i.e.…”
