Removal of Air Pollutants Using Graphene Nanocomposite

Currently, environmental pollution becomes a global issue because of rapid industrial and socioeconomic development in developing countries. The quality of air is determined by many factors like temperature, humidity, and the concentration of the pollutants. These factors affect the quality of the air and continuously contaminate the fresh air. Wastewater treatment is also an urgent need to regulate the air pollution present in the environment. In the present studies, graphene, composite, nanofibers, and adsorbents are trending for remediation of water pollutants found in water. At the same time, researchers tried to control air pollution by using the same materials. In this chapter, we mainly focus on the air pollution and their respective pollutants as, carbon dioxide (CO2), nitrogen oxide (NOx), sulfur dioxide SO2, particulate matter (PM2.5 and PM10), lead, and the volatile organic compounds (VOCs). These are the main constituents of air pollution. Several filters and ion-based composites, hybrids functionalization, and synthesis methodologies are using toward keeping the indoor and outdoor air quality.
