A continuous growth in the world population and an accompanying industrial revolution is causing several serious environmental problems. Among these, a rapid pollution of waterbodies due to the discharge of huge quantities of industrial wastewater, is a great concern for the society. Excess organic chemicals, such as dyes in the rubber, plastic, cosmetics and textile industry are released into the environment on regular basis. Most of these dyes are non-biodegradable and can be carcinogenic in nature. Considerable efforts have been devoted to produce efficient technological solutions for the removal of such dyes from polluted water. These include coagulation, adsorption, chemical degradation and photocatalytic degradation. Among these, coagulation and adsorption convert dissolved pollutants from into solid form. Most of the conventional approaches suffer from limitations, either associated with a high cost of the procedure or the inherent stability of the dyes against degradation.
