钼酸铜纳米片的制备及其气敏性能
Preparation of copper molybdate nanosheets and gas sensing performances
摘要
Abstract
Copper molybdate(Cu3Mo2O9)with nanosheet structure is synthesized by a hydrothermal method.The morphology,structure,and specific surface area of the sample are characterized by techniques such as SEM,XRD,and EDS.Two gas sensors are fabricated with Cu3Mo2O9 nanosheets and MoO3 nanorods as sensing materials.The sensing performances of the two sensors for volatile organic gases are tested.It is found that when the sensors are exposed to 100×10-6 acetone,the Cu3Mo2O9 sensor shows an ultra-high response of 145.4 at 210℃.This response is about 2.1 times that of the MoO3 sensor(67.8).The response/recovery time are 29.7 s/21.2 s,respectively.The excellent cycling stability of the Cu3Mo2O9 sensor is demonstrated by 10-cycle tests exposed to 100×10-6 acetone.Its excellent sensing properties are attributed to its porous nanosheet structure and the synergistic interaction between the two metal elements copper and molybdenum.The structure has a large specific surface area,providing a large number of surface active sites for the adsorption of gas molecules,promoting the redox reaction between gases.Cu3Mo2O9 nanosheet sensor shows excellent sensing properties for acetone,indicating that it has great potential in the practical detection of acetone gas in the future.关键词
