Certification Course on Advanced Nano Materials Synthesis, Characterization, and Their Photoelectrocatalytic Applications

In the present situation where there is a water shortage globally, nanoparticles can play a vital role in treating waste water to make it usable for several processes. Industrial waste water contains numerous heavy metals and associated wastes that enter our food chain by one means or other. This course will provide an overview of the applications of nanoparticles in waste water treatment and energy and environmental applications. Several contaminants can be eliminated from wastewater bodies using photocatalytic nanoparticles. The efficiency of photocatalytic nanoparticles can be enhanced by coupling them with suitable species. Research in this area can prevent the water shortage in the future.
