Abstract
After the discussion of all the preceding sections/chapters, now we are in a position to review some typical nanomaterial systems that have established themselves as materials of immense potential in the field of water purification by successfully removing different textile dyes through different processes like catalysis adsorption or others. In this chapter, we will discuss a few such particular materials from different domains. The material will mainly include metal oxide nanostructures and related derivatives like zinc oxide, etc., and also carbon nanostructures like carbon nanotube, graphene, etc., and their hybrids. A detailed discussion regarding the dye removal ability of graphitic carbon nitride is also included here. In this regard, the results of other researchers will be accompanied by a few of our own findings, which will help the reader in better understanding the topic. Apart from these wellknown materials that have higher dye removal effectiveness, a few other less studied and newly evolved systems, such as silicon nanowire and p-type conducting oxides like copper borate, have also been discussed with a few established results.
