Composite

Adsorption is one of the most researched topics in the field of nanochemistry nowadays. Their fascinating properties of nanocomposites allow them to be used in numerous industries including conducting inks, clothes, colorimetric sensors, electrochemical sensors, biosensors, adsorption, etc. Due to their very small size, these nanocomposites have efficiently been employed as adsorbents. Their enhanced adsorption properties have been used for the removal of pollutants that have become a part of our environment due to anthropogenic activities. There are various kinds of nanocomposites including clay nanocomposites, hybrid nanocomposites, metal oxide-based nanomaterials, carbon nanotubes, and various polymeric nanocomposites, which have been tested as adsorbents for the removal of a variety of heavy metals, such as arsenic, cadmium, cobalt, chromium, copper, mercury, manganese, nickel, lead, tin, and zinc from the aqueous medium according to the published research in the recent past. In addition to the utilization of nanocomposites alone, they have also been used along with the modern wonder materials, i.e., graphene, single and multi-walled carbon nanotubes, and in the making of their hybrid materials that have exceptional properties as compared to their constituents. This chapter emphasizes on the adsorptive efficacy of various kinds of nanocomposites and their derivatives as well as a variety of pollutants along with their other general adsorptive applications.
