In recent years, the detrimental effects of air pollution on human health and the environment have become increasingly evident. Traditional methods of air pollution control often fall short in effectively mitigating the growing challenges posed by pollutants. Nanotechnology has emerged as a promising avenue for tackling air pollution due to the unique properties of nanomaterials. This chapter explores the diverse applications of various nanomaterials in air pollution remediation, including their synthesis, mechanisms of pollutant removal, and potential environmental implications. This research explores the multifaceted application of various nanomaterials in the realm of air pollution remediation, a critical field of environmental science. It delves into the diverse array of nanomaterials, ranging from metal oxides to carbon-based nanomaterials, and their pivotal roles in mitigating air pollutants such as particulate matter, volatile organic compounds, nitrogen oxides, and sulfur dioxide. This study elucidates the underlying mechanisms through which nanomaterials interact with pollutants, including adsorption, catalysis, and photocatalysis, thus elucidating their efficacy in air purification. Furthermore, it scrutinizes the challenges and prospects associated with the implementation of nanomaterial-based remediation strategies, encompassing considerations of scalability, cost-effectiveness, and environmental impact. This chapter culminates in highlighting the promising avenues for future research and development, underscoring the imperative of harnessing nanotechnology to combat the burgeoning menace of air pollution and foster sustainable environmental stewardship.
