Abstract
The growth of industries and other human activities have led to ever increasing amounts of pollutants in both outdoor and indoor spaces. These pollutants have hazardous effects on humans and the wider ecology. Hence, air quality monitoring (AQM) is essential and involves the robust monitoring of various toxic gases and volatile organic compounds (VOCs)-in case the concentration of any pollutant exceeds the safe limit in a given location. This paper describes the different sources of indoor and outdoor pollutants, reviews the current status of gas sensors, and discusses the role of new two-dimensional (2D) materials in detecting these hazardous gases at low power, i.e. close to ambient temperature. Here we review different synthesis techniques of 2D materials and discuss the sensing performances of pristine and functionalized nanomaterials for some of the important pollutants like NOx, NH3, SOx, CO, formaldehyde and toluene. The review concludes with some proposed methods to help reduce air pollution today.
