The world's persistent daily development continues to cause unceasing
damage to the air. As reported by the World Health Organization, over six million
people worldwide lost their lives due to residing and working in environments affected
by air pollution in 2016. Despite the effectiveness of traditional techniques such as
desulfurization, denitrification, and dust removal in reducing emissions from the
sources of stationary combustion, they have not proven successful in reducing the
frequency of atmospheric haze conditions. Current research globally urges the
advancement of technologies to create nanomaterials (NMs) capable of efficiently and
intelligently trapping CO2
, CO, and other harmful gases from the air. Diverse NMs play
pivotal roles as nano adsorbents, nanocatalysts, nanofilters, and nanosensors,
showcasing the versatility and effectiveness of nanotechnological applications in this
field. This technology facilitates air pollution remediation by treating volatile organic
compounds, greenhouse gases, and bioaerosols through adsorption, photocatalytic
degradation, thermal decomposition, and air filtration processes. This chapter
specifically delves into the practical use of a range of NMs for air pollution
remediation applications.
