摘要:We report here the fabrication of SnO_2 thick film and SnO _2 porous nanosolid CO gas sensors by using SnO_2 nanoparticles and porous nanosolid (PNS). It is found that the thick film sensor fabricated from SnO_2 PNS has lower intrinsic resistivity than the one fabricated from SnO_2 nanoparticles, and the sensor response of the former is higher than that of the latter. On comparison, the SnO_2 PNS sensor, prepared by directly coating Au electrodes on the opposite surfaces of a SnO_2 PNS, possesses both lower intrinsic resistivity and higher sensor response to CO gas. Furthermore, the SnO_2 PNS sensor also has much lower working temperature, and it can be used as a dual functional gas sensor, i.e., as CO sensor at 300 °C and as CH_4 sensor at 400 °C, respectively.
