NASICON-based CO2 sensor taking Co3O4-Li2CO3 as sensitive electrode and preparation method of NASICON-based CO2 sensor
The invention discloses an NASICON-based CO2 sensor taking Co3O4-Li2CO3 as a sensitive electrode and a preparation method, and belongs to the technical field of solid electrolyte type gas sensors. The sensor is composed of an Al2O3 ceramic tube, an NASICON substrate layer, a reference electrode and a sensitive electrode. The NASICON substrate layer is uniformly coated on the outer surface of the Al2O3 ceramic tube, the reference electrode and the sensitive electrode are positioned at the two ends of the outer surface of the NASICON substrate layer, and a nickel-cadmium heating coil is arranged in the ceramic tube in a penetrating manner to provide proper working temperature for the sensor; according to the present invention, the sensitive electrode material is Co3O4-modified Li2CO3, the mass fraction of Co3O4 is 5-20%, the experiment results show that the Co3O4-modified Li2CO3 effectively improves the response performance of the sensor, and the 10% wt Co3O4-modified Li2CO3 sensor has the optimal response characteristic.
一种以Co3O4‑Li2CO3为敏感电极的NASICON基CO2传感器及制备方法，属于固体电解质型气体传感器技术领域。由Al2O3陶瓷管、NASICON基体层、参考电极和敏感电极组成；NASICON基体层均匀地涂覆在Al2O3陶瓷管的外表面，参考电极和敏感电极位于NASICON基体层外表面的两端，在陶瓷管内部穿有镍镉加热线圈为传感器提供适宜的工作温度；敏感电极材料为Co3O4修饰的Li2CO3，其中Co3O4的质量分数为5～20％，实验发现Co3O4修饰的Li2CO3有效地改善了传感器的响应性能，且10％wt Co3O4修饰的Li2CO3传感器具有最佳的响应特性。
