Clean and drinkable water is a big challenge in 21st century. A variety of organometallic compounds have been utilized by human being for rapid civilization and modernization. These hazardous waste discharges from the industries and directly mixed with environment especially in water reservoir and adulterate water, which is responsible for many contagious diseases. To vanquish this issue we needed an eco-friendly, safe, cost-effective nanomaterials for the degradation and removal of noxious waste. In this chapter emphasized on different nanomaterials as photocatalyst for photocatalytic performances, also critically discussed applicability of different nanomaterials for photocatalytic process comprising with types photocatalyst, light source, scavengers, trapping agents, photodegradation activity mechanism and its utility. Moreover, removal of toxic dyes, pharmaceutical drugs, agrochemical waste, heavy metal ions, and phenolic compounds have been discussed.
