摘要：
Pt/SnO2 core-shell nanowires were prepared by a process that involves thermal evaporation of SnO2 nanowires and subsequent atomic layer deposition of Pt, and their gas- and photon-sensing properties were investigated systematically. Transmission electron microscopy analysis showed that the Pt shell with a thickness of 8.8 nm is composed of numerous Pt nanoparticles with average diameters of similar to 5.3 nm. The Pt/SnO2 core-shell nanowires with high electrical conductance exhibit remarkably enhanced ethanol gas-and photon-sensing properties due to the surface functionalization resulting from the effective Pt catalyst and the formation of hetero-nanostructures fabricated by the SnO2 core and Pt shell.
