Role of Carbon Nanomaterials in Air Pollution Remediation

Globally, air pollution is a huge problem that impacts both the natural environment and the well-being of humans. The most recent advances in nanotechnology can help with potential remedies for the problems associated with air pollution and significantly improve the selectivity and efficacy of air cleansing systems, resulting in cost-effectiveness and more long-term performances. With the use of nanotechnology, air pollution could be reduced through a variety of methods, including using nanocatalysts, nanoadsorbents, nanosensors, and so on. The nanoparticles can adsorb or absorb several airborne pollutants. By employing the arrangement and size of the materials at the nanoscale form, nanotechnology is an innovative branch of science that may solve a wide range of environmental problems. For the reason of their benign nature, large surface area, ease of biodegradation, and mainly relevant environmental monitoring properties, carbon nanomaterials are distinctive. However, the use of carbon nanomaterials and nanotechnology is confronted with a number of difficulties, including production costs, toxicity, environmental hazards, and public acceptance. So, CNMs have advantages and disadvantages discussed in this chapter. The main emphasis of this chapter is the usage of CNMs in applications for air pollution remediation. Mainly, we discussed different types of carbon nanomaterial structures, properties, and removal mechanisms of different air pollutants.
