Graphene oxide (GO) is an excellent suitable material as a gas-sensing layer due to its adsorption ability towards toxic gas molecules. In this work, GO nanosheets (GO-NSs) were employed in a mass-type toxic gas sensor using a quartz crystal microbalance (QCM) transducer. The sensor was prepared by spraying the GO-NS suspension on the working electrode surface of the QCM. The gas-sensing properties of the sensor were examined with various concentrations of toxic gases, including NO₂, SO₂, CO, and NH₃. The results demonstrated that the adsorption potential of the prepared GO-NSs makes them a promising candidate for the sensing layer of mass-type gas sensors to detect toxic gases.

氧化石墨烯（GO）由于其对有毒气体分子的吸附能力，因此非常适合用作气体传感层。在这项工作中，GO纳米片（GO-NSs）被用于使用石英晶体微量天平（QCM）传感器的质量型有毒气体传感器中。通过将GO-NS悬浮液喷涂在QCM的工作电极表面上来制备传感器。使用各种浓度的有毒气体（包括NO ₂，SO ₂，CO和NH _3）检查了传感器的气敏特性。结果表明，所制备的GO-NSs的吸附潜力使其成为用于质量型气体传感器检测有毒气体的传感层的有希望的候选者。
