ABSTRACT
The exceptional and fascinating properties of carbon-based nanomaterials such as graphene, nanotubes, and fullerene provide a novel horizon for unraveling environmental concerns. Carbonaceous nanomaterials have substantially contributed to numerous environmental applications like adsorption and membrane separation of pollutants such as heavy metals, dyes, pesticides, environmental sensors, photocatalytic degradation of toxic compounds, and so forth. In this chapter, synthesis, modification of major carbon-based nanomaterials and their applications are discussed. An insight into the possible environmental remediation by carbonaceous and modified carbonaceous nanomaterials in areas such as sensing, removal, and degradation of environmental pollutants have been presented. The environmental hazard materials can be successfully adsorbed and eliminated by eco-friendly nano-polysaccharides. This chapter also discusses the potent toxicity of various nanomaterials including carbonaceous materials, quantum dots, and metal–metal oxide nano-forms.
