This　paper　describes　that　high-yield　Ag/C　coaxial　nanocables　has　been　obtained　via　a　simple　hydrothermal　approach　through　the　in　situ　reaction　of　Ag+　and　glucose　in　the　condition　of　CTAB.　The　glucose　not　only　acts　as　reducing　agent　but　also　as　carbon　source.　It　was　found　that　high　aspect　ratio(＞400)of　nanocables　with　Ag　nanowires　core　diameter　(20-60)nm　and　various　carbon　shell　thickness　had　been　prepared　in　large　scale　with　a　facile　aqueous　reduction　route　at　low　temperatures　for　different　times.　All　of　the　products　were　characterized　in　detail　by　multiform　techniques:　X-ray　diffraction(XRD),　transmission　electron　microscopy(TEM),　high-resolution　TEM(HRTEM),　scanning　electron　microscopy(SEM),　energy-dispersive　X-ray　spectroscopy　(EDX).
