Abstract

The ZnO nanowires (NWs) are grown by carbothermal reaction and SnO 2 shell layers are subsequently coated by vapor phase growth. The crystalline SnO 2 shell layer with the thickness of 5-20 nm was uniformly coated on the ZnO NWs with the diameter of 50-100 nm. The gas response of ZnO-SnO 2 core-shell NWs sensor to 10 ppm NO 2 at 200°C was increased up to ∼33 times compared to those of ZnO NWs. The enhancement of gas responses to NO 2 was discussed in relation to the thin SnO 2 shell layer and core-shell configuration of NWs.
