This book offers readers with analysis of the main causes of air pollution and related functional materials application and research.Air, as the primary element on which human life depends, directly impacts human living and health. However, a 2022 report from the World Health Organization indicated that "the air nearly the entire global population (99%) breathes exceeds WHO air quality limits, threatening their health". Currently, the main approaches to air pollution involve source control and the treatment of air pollutants, with significant emphasis on the research and application of functional materials.With the development of material science, an increasing number of high-performance materials have been introduced into the field of air pollution control and have achieved good results. For instance, nanocomposite materials and bio-based materials. In addition, novel sensing materials have also enabled us to monitor air pollution more stably and accurately, especially for specific pollutants. Moreover, they play a crucial role in understanding the distribution, sources, and trends of pollution.It provides engineers and researchers in the field of air pollution control with research findings related to this area and the corresponding functional materials. It aims to share specific and valuable knowledge and content to improve air pollution control efforts.
