摘要
科技的发展和生产力水平的不断提高,给人们生活带来极大便利的同时,由于能源消耗及其附加污染物的生成,环境面临巨大的挑战。其中大气污染是我们关注的主要方面之一。NO2作为一种主要的大气污染物,对水体、土壤和大气都会造成极大威胁,如地表水、土壤酸化以及光化学烟雾等。同时对人体健康也有很大危害,如引发呼吸道疾病和心脑血管疾病。因此,制备适用于环境监测且工作温度和检测限较低且灵敏度高的便携式气体传感器来确定环境中NO2浓度的大小十分重要。本文概述几种典型的N型半导体金属氧化物NO2气体传感器的研究进展,对NO2传感器在环境监测方面的应用和今后的研究方向进行了展望。
The development of science and technology and the continuous improvement of productivity have brought great convenience to people’s lives.At the same time,due to energy consumption and the generation of additional pollutants,the environment is facing huge challenges Among them,air pollution is one of our main concerns.As a major air pollutant,NO2 poses a great threat to water bodies,soil and atmosphere,such as surface water,soil acidification and photochemical smog,etc..Meanwhile,it is also harm to human health,for example respiratory diseases,cardiovascular and cerebrovascular diseases.Therefore,it is essential to prepare a portable gas sensor that is suitable for environmental monitoring and has low operating temperature,detection limit and high sensitivity to determine the NO2 in the environment.This article summarizes the research progress of several typical N-type semiconductor metal oxide NO2 gas sensors,and prospects the application of NO2 sensors in environmental monitoring and the future research directions.
