Acetone sensor based on metal ion doped cerium dioxide aerogel, preparation method and application of acetone sensor in acetone detection
The invention discloses an acetone sensor based on metal ion doped cerium dioxide aerogel, a preparation method and application of the acetone sensor in acetone detection, and belongs to the technical field of gas sensors. The sensor consists of an Al2O3 ceramic tube substrate, two parallel and independent annular Au electrodes coated on the outer surface of the Al2O3 ceramic tube substrate, gas sensitive films coated on the outer surface of the Al2O3 ceramic tube and the annular Au electrodes, and a nichrome heating coil penetrating through the inside of the Al2O3 ceramic tube. The material of the gas sensitive film is metal ion doped cerium dioxide aerogel with a porous structure, metal ions are cobalt, copper, manganese and the like, and the abundant porous structure is beneficial to increasing the number of surface active sites of the material and increasing the diffusion speed of gas molecules and reaction products; the sensor based on the metal ion doped cerium dioxide aerogel prepared by the invention has an ultrafast response recovery rate to acetone, and has a good application prospect.
一种基于金属离子掺杂二氧化铈气凝胶的丙酮传感器、制备方法及其在丙酮检测中的应用，属于气体传感器技术领域。传感器由Al2O3陶瓷管衬底、涂覆在Al2O3陶瓷管衬底外表面的两条平行且彼此分立的环状Au电极、涂覆在Al2O3陶瓷管外表面和环状Au电极上的气体敏感薄膜、穿过Al2O3陶瓷管内部的镍铬合金加热线圈组成。气体敏感薄膜的材料为具有多孔结构的金属离子掺杂二氧化铈气凝胶，金属离子为钴、铜、锰等，丰富的多孔结构有利于提高材料的表面活性位点数量、提高气体分子和反应产物的扩散速度，本发明所制备的基于金属离子掺杂二氧化铈气凝胶的传感器对丙酮具有超快的响应恢复速率，具有良好的应用前景。
