چکیده انگلیسی
Selective noxious gas sensing at low temperature is very important in some industrial applications. Here, we demonstrate that the reduced graphene oxide (RGO) wrapped Au@ZnO core-shell composite can be fabricated in wafer-level and used as the key sensor materials for triethylamine sensing with a high response of 12.2% for 5âppm of TEA gas at a low temperature (50â°C). The sensitivity of RGO/Au/ZnO sensor to TEA gas achieved almost 6 times higher than that of ethanol and acetone, 5 times that of methanol and isopropanol, and 3 times that of ammonia. The selective sensing properties are largely attributed to the synergistic effect of the core-shell structure and the ZnO/RGO heterojunctions. This work provides a significant strategy for TEA gas sensor selective sensing arrays application at low temperatures.
