ABSTRACT
Green nanotechnology is based on the 12 principles of green chemistry to synthesize new nanomaterials to attain, health, economic, environmental, and social benefits. Carbon in its single entity and various forms has been used in technology and human life for many centuries. Since in the prehistoric times, carbon-based materials have been used as writing and drawing materials. In the past two and a half decades, carbon nanomaterials (CNs), especially carbon dots (CDs), carbon nanotubes (CNTs), graphene, fullerenes, and carbon nanodiamond (ND) have been used as efficient materials due to their exclusive properties. The new green methods and technologies associated with CNs are put forward by the researchers all over the world have opened exciting opportunities for the revolution of green nanotechnology. CNs such as graphene, fullerenes, CNTs, NDs, and CDs synthesized from renewable organic resources have gathered a considerable amount of attention due to their outstanding properties and applications. The latest trends in the green synthesis and properties of the CNs are presented here for generating social awareness about the sustainable developments.
