CARBONACEOUS NANOMATERIALS FOR WATER POLLUTION REMEDIATION: AN OVERVIEW

Abstract

Any Material, having structure in nanometer scale with at least one dimension is recognized as Nanomaterial (NM). These Nanomaterial (NMs) have vast variations in their elemental composition; which may be formed by single element viz. Gold, Silver, Iron, Carbon etc. or by the combination with Oxygen or Sulphur as Oxides & Sulphides viz. Iron oxide (Fe2O3), Copper Oxide (CuO) or Cadmium Sulphide(CdS),etc. Among the single elemental forms, the Carbonaceous Nanomaterials(CNMs) are identified as nanosized allotropic forms of Carbon having different structures like Nano rods, Nano tubes, Nano ring, Nano sphere, and Nano sheets mostly with sp2 carbon atoms. In past decades, Carbonaceous Nanomaterials(CNMs) have gain interest of researchers due to their biocompatibility, non-toxicity and unique surface to volume properties, etc. their easy tunable features are found advantageous for their utilization in wide range of applications. Further, owing to their specific mechanical strength, conductivity, surface activity and many more beneficial features, they have vast range of applicability in electronic, biomedical, energy storage & conversion, catalysis and remediation of environmental pollution. Present paper briefly describes about the types of Carbonaceous Nanomaterials (CNMs) with emphasizing their use in the remediation of Water Pollution. With the growing development of Nanotechnologies, use of CNMs may play a significant role in remediation of Water Pollution.
