Carbon Nanotubes for A Greener Environment

Abstract

Reckless human activities have a negative impact on the environment. Hence, there is a need for the development of technologies that help to give a new dimension to the eco-friendly environment. The advancement in the field of nanotechnology provides so many multifunctional materials that help in making the environment more sustainable and greener. Many multifunctional materials like carbon nanotubes (CNTs), quantum dots, graphene augur well for such applications. Recent progress in the frontiers of nanotechnologies has supported benchmarking CNTs as one of the most investigated carbon-based nanomaterials. A plethora of applications of CNTs has been proposed in various fields of research due to their unequaled physical, chemical, optical, and electronic properties. This chapter points out the contribution of CNTs in terms of sustainable environment and eco-friendly technologies perspectives like wastewater treatment, air pollution monitoring, desalination, renewable microbial fuel cells, supercapacitors, and green nanocomposites. Based on the available reports, CNTs proved to be a promising candidate for application in various environmental fields.
