Carbon Nanoadsorbents

Carbon is one of the highly explored materials because of its exceptional properties such as high chemical stability, superior mechanical strength, catenation property, anisotropy and conductivity. Researchers have investigated numerous morphologies of carbon, specially at the nanoscale for their utilization in the advancements of various operational areas. This chapter deals with the overview of various carbon based nanoadsorbents (CNs): Carbon nanotubes (CNTs), Graphene and its derivatives, fullerenes and carbon quantum dots (CQDs). The structure, exceptional properties and synthetic strategies of these nanoadsorbents have been discussed and compared. The shifts and advancements in these strategies were observed towards a greener perspective, so that CNs can be adopted as a suitable and efficient alternative for conventional techniques of water purification.
