The removal of emerging contaminants from the environment has been an issue of top priority in recent times due to their adverse ecological effects. Nanomaterials have proven their worth in the search for effective and efficient remediation materials for wastewaters. The chemical methods of nanomaterial synthesis with co-precipitation being the simplest and the biological methods using plants provide ease of fabrication and make them economical too. Characterizations are done using different techniques such as powder XRD, electronic microscopy, atomic force microscopy and thermogravimetric analysis and these give information about the morphology, particle size, impurities, roughness, thermal stability and degradation pattern of nanomaterials. Nanomaterials often find application in adsorption, photocatalysis, catalytic ozonation, membrane process and nanoremediation of environmental pollution.
