In this study, a Pb-Sn alloy nanowire of 80 nm in diameter and 50 microm in length is obtained by an anodic aluminum oxide nanomold and vacuum die casting method. The upper and lower ends of the prepared Pb-Sn alloy nanowire array are vapor deposited with 3 microm of copper thin film, which serves as the conductive layer of the gas sensor. Experimental results show that the sensitivities of 3 gas sensors fabricated by 3 different Sn-Pb alloy nanowire arrays, namely Sn70%-Pb 30% wt, Sn63%-Pb 37% wt and Sn50%-Pb 50% wt, for detecting a carbon monoxide concentration of 500 ppm under a working temperature of 250 degrees C, were 17.83%, 14.89% and 14.12% respectively.
在本研究中，通过阳极氧化铝纳米模具和真空压铸法制备了直径为80纳米、长度为50微米的铅锡合金纳米线。在所制备的铅锡合金纳米线阵列的上下两端气相沉积3微米厚的铜薄膜，其作为气体传感器的导电层。实验结果表明，由三种不同的锡铅合金纳米线阵列（即Sn70%-Pb 30% wt、Sn63%-Pb 37% wt和Sn50%-Pb 50% wt）制备的三个气体传感器，在250℃的工作温度下检测500 ppm一氧化碳浓度时，灵敏度分别为17.83%、14.89%和14.12%。
