Abstract

The development of a MoS₂/CuO composite for acetone gas sensing at room temperature represents a significant advancement in the field of chemical sensors. This study presents the fabrication and characterization of a highly sensitive and selective acetone gas sensor based on a MoS₂/CuO heterojunction. The resulting composite exhibited a well-defined heterojunction, which is crucial for enhancing gas adsorption and sensor response. The MoS₂/CuO sensor demonstrated excellent performance in detecting acetone at room temperature, with an excellent response (7.01), short response and recovery times (85/177 s), and good selectivity than other testing gases. The gas sensing mechanism was attributed to the modulation of the depletion region at the MoS₂/CuO interface upon acetone adsorption, which led to a significant change in the sensor electrical resistance. The results indicate that the MoS₂/CuO composite is a viable material for the development of low-cost, efficient acetone sensor operating at room temperature.

释放MoS2/CuO纳米结构用于丙酮检测的潜力

室温丙酮气体传感用MoS2/CuO复合材料的研制是化学传感器领域的一个重大进展。本研究提出了一种基于MoS2/CuO异质结的高灵敏度和选择性丙酮气体传感器的制备和表征。所得到的复合材料表现出良好的异质结，这对增强气体吸附和传感器响应至关重要。在室温条件下，MoS2/CuO传感器具有良好的丙酮检测性能，具有良好的响应（7.01）、较短的响应和恢复时间（85/177 s）和较好的选择性。丙酮吸附后，MoS2/CuO界面的耗尽区发生了调制，导致传感器电阻发生了显著变化。结果表明，MoS2/CuO复合材料是开发低成本、高效的室温丙酮传感器的可行材料。
