What are the benefits of using nanomaterials for water purification?

Nanomaterials offer several advantages for water purification. They provide a higher surface area-to-volume ratio, enhancing the adsorption of contaminants. For instance, titanium dioxide (TiO2) nanoparticles can be used for photocatalytic degradation of organic pollutants under UV light. Similarly, silver nanoparticles have antimicrobial properties that can effectively kill bacteria and viruses, making them useful for disinfecting drinking water. Additionally, nanofilters made from materials like graphene oxide can selectively remove heavy metals and other toxic substances from water.
