摘　　要：由于温室效应越来越严重,开发一种性能优异的二氧化碳传感器对其进行高效、准确地检测具有现实意义。本论文旨在于能够成功地制备出Na_(3)V_(2)(PO_(4))_(3)试样来对CO_(2)的气敏性能进行研究。采用高温固相球磨法以及溶胶凝胶法制备了NVP材料,采用高温固相法合成了NASICON粉体,运用XRD、SEM技术研究了NVP与NASICON的晶体结构与微观形貌。以NASICON为固体电解质,以NVP为对电极材料,组装出了片式CO_(2)气体传感器,并进行了气体传感器性能研究。结果表明,传感器的最佳工作温度为150℃,在该温度下的灵敏度为2.03 nA/ppm。Because of the more and more serious greenhouse effect,it is of practical significance to develop a kind of gas sensor with excellent performance to detect low concentration carbon dioxide efficiently and accurately.The aim of this paper is to prepare Na_(3)V_(2)(PO_(4))_(3) sample successfully to study the gas sensitivity of CO_(2).In this paper,NVP material was prepared by high temperature solid phase ball milling method and sol-gel method.NASICON powder was synthesized by high temperature solid phase method.XRD and SEM techniques were used to study the crystal structure and microstructure of NVP and NASICON.Using NASICON as solid electrolyte and NVP as electrode material,a chip CO_(2) gas sensor was assembled and its performance was studied.The results show that the optimal operating temperature of the sensor is 150℃,and the sensitivity is 2.03 nA/ppm at this temperature.
