N2 - Our previous work on the electrodeposition of Re alloys with the iron-group metals has been extanded in the present work to study the Re-Sn system. Sn was also codeposited with Re, but the resulting structure was quite different from that obtained with the iron-group metals. Core/shell structures of nanowires (NWs) were observed, in which crystalline Sn is the core and amorphous Re is the shell. A mechanism was suggested acording to which Sn nanowires were first grown on top of Sn microparticles. Next, metallic Sn reduced the perrhenate ion, forming a shell of Re. This mechanism was confirmed by electroless deposition of Re on thin film of Sn. It is consistant with the mechanism proposed in our previous work, where Ni, Co or Fe were initially reduced to the metallic form and further acted as a reducing agent for reduction of the perrhenate ion to metallic Re.
