Progress of NASCION-based electrochemical gas sensors

NASCION基气体传感器具有响应快、灵敏度高、稳定性好等优点,因此得到广泛的关注。相比于其它固体电解质,NASCION固体电解质(Na_(1+x)Zr_(2)Si_(x)P_(3-x)O_(12)(0≤x≤3))属于钠超离子导体,具有优良的Na^(+)电导率。近年来国内外有不少关于NASCION基气体传感器的研究论文,但综述类文章较少。本文综述了NASCION基电化学气体传感器的原理,总结了NASCION基气体传感器对NO_(x)、SO_(2)、CO_(2)等气体的研究进展。并详细介绍了敏感电极材料和传感器结构对传感器性能的影响,对NASCION基固体电解质的气体传感器做出展望。

The NASCION-based gas sensor have received wide attention from researchers for their advantages of fast response,high sensitivity and good stability.Compared to other solid electrolytes,NASCION Solid electrolyte(Na_(1+x)Zr_(2)Si_(x)P_(3-x)O_(12)(0≤x≤3))belongs to the sodium superion conductor and has excellent Na^(+)conductivity.In recent years,there are many research papers on NASCION-based gas sensors at home and abroad,but there are few review articles.This paper summarizes the principle of NASCION-based electrochemical gas sensors and summarizes the progress of NASCION-based gas sensors on NO_(x),SO_(2),and CO_(2),etc.The effects of the sensitive electrode material and the sensor structure are also described in detail,and prospects the field of the gas sensor of the NASCION-based solid electrolyte.
