基于钙钛矿型复合氧化物半导体的二氧化碳传感器
CO2 sensor based on perovskite-type oxide semiconductor
摘要
Abstract
In situ monitoring of CO2 emission is crucial for its proper disposal.At present,due to the limitations of the commonly used CO2 sensors,the resistive sensors are gradually becoming a research hotspot for CO2 detection.However,there are few types of sensitive materials suitable for the resistive CO2 sensors,resulting in restricted selection/regulation range and performance optimization challenges.In this paper,Co was introduced into Ba3MgNbFeO9-δ by the conventional solid sintering method to prepare perovskite-structured Ba3MgNbFe1-xCoxO9-δ(BMNFC)compounds,and the performance of CO2 sensors based on BMNFCs was investigated.The results show that the prepared sensors exhibited good sensitivity to CO2,and the sensitivity was enhanced as the Co dopant content was increased.Among the synthesized BMNFCs,Ba3MgNbFe0.25Co0.75O9-δ(BMNFC75)exhibited better stability and CO2 sensitivity than others.By using BMNFC75 as the sensitive material,a CO2 sensor with good response/recovery characteristics,in-situ monitoring capability,wide operation temperature range,and low applied external voltage is expected to be developed.This work provides insights for the application of multi-element-doped perovskite-type semiconductors in CO2 sensors.关键词
