Pradeep’s work is in the area of molecular materials and surfaces.
His group discovered that noble metal nanoparticles degrade halocarbons efficiently to amorphous carbon and metal halides at room temperature and at low concentrations. This discovery has led to the world’s first nanochemistry based water filter for pesticide removal as many pesticides of relevance are halocarbons. This technology is estimated to have reached about 9 million people. His group developed several technologies to remove other contaminants from drinking water. Combining several such materials, an all-inclusive affordable drinking water purifier has been developed. Exciting aspect of this technology is the creation of advanced materials by simple and environment-friendly methods. This technology, named AMRIT, is being implemented now in the arsenic affected regions of India. About one million people have been benefitted from these installations. Several other drinking water technologies have been rolled out from his lab.
To take such technologies forward, four companies have been incubated with the participation of IIT Madras. This activity is now being expanded globally.
