Abstract
Sn doped CuO nanotubes were synthesized by thermal oxidization of Cu/SnO2 core--shell nanowires in air through the Kirkendall effect. The Cu/SnO2 core--shell nanowires were sequentially electrodeposited by forming a SnO2 shell followed by electrodeposition of the Cu core. After thermal treatment in air, the core--shell Cu/SnO2 (13 plus or minus 2 nm thick shell on 128 plus or minus 15 nm in diameter core) nanowires were oxidized to form Sn doped CuO nanotubes with an average wall thickness and outer diameter of 54 nm and 176 nm, respectively. Room temperature I--V characterization indicated that the electrical resistivity of the nanostructures was 870 plus or minus 85 Delta *W cm. The methodology that was demonstrated is very general and could be used to synthesize coaxial SnO2 shells with a variety of electrodeposited cores. In addition, doped metal oxide nanotubes can be readily synthesized by thermal oxidization of core--shell nanowires in air where the dopant content can be tuned by controlling the shell thickness through adjusting the deposition time.
