Abstract
A study on the low-temperature CO gas sensors based on Au/SnO2 thick film was reported. Au/SnO2 powders, with different Au loading from 0.36 to 3.57 wt%, were prepared by a deposition–precipitation method. Thick films were fabricated from Au/SnO2 powders. The Au/SnO2 thick-film sensors exhibited high sensitivity to CO gas at relatively low operating temperature (83–210 °C). We also reported the effect of the Au loading in Au/SnO2 on the CO gas sensing behavior. The optimal Au loading in as-prepared Au/SnO2 was 2.86 wt%.
