| 摘要: 采用共沉淀法制备了CuGa2O4纳米材料，并利用水热法制备了一系列WS2/CuGa2O4复合材料。结合X射线衍射(XRD)、扫描电子显微镜(SEM)、X射线光电子能谱(XPS)等对制备的材料进行了物相组成、表面形貌以及元素价态的分析。研究了WS2的复合量对CuGa2O4材料检测乙醇气体敏感性能的影响。实验结果表明，当WS2与CuGa2O4质量比为1%时，该复合材料制备的传感器在室温下对100 μL·L-1乙醇气体表现出345.3的灵敏度，响应时间和恢复时间分别为184和69 s，且最低检测限为0.1μL·L-1。 | |

| Abstract: CuGa2O4 nanomaterials were synthesized by the co-precipitation method, and a series of WS2/CuGa2O4 composite materials were prepared by the hydrothermal method. The crystal phase, morphology, and chemical state of the as-prepared materials were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and so on. The effect of the doped amount of WS2 on the gas-sensing sensitivity of CuGa2O4 materials to ethanol gas was studied. The results showed that when the mass ratio of WS2 to CuGa2O4 was 1%, the response of this gas sensor to 100 μL·L-1 ethanol gas at room temperature was 345.3, and the response and recovery times were 184 and 69 s, the detection limit reached 0.1 μL·L-1. | |
