Nanomaterials as Photocatalyst

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 modernization. These hazardous waste discharges from the industries directly mixed with environment especially reservoir adulterate water, which responsible many contagious diseases. To vanquish this issue we needed an eco-friendly, safe, cost-effective nanomaterials degradation removal noxious waste. In chapter emphasized on different as photocatalyst photocatalytic performances, also critically discussed applicability process comprising types photocatalyst, light source, scavengers, trapping agents, photodegradation activity mechanism its utility. Moreover, toxic dyes, pharmaceutical drugs, agrochemical waste, heavy metal ions, phenolic discussed.
