CHAPTER 7: Photocatalytic Nanocomposites for Environmental Remediation

The wastewater problem is a worldwide problem that is experienced by every single country. In total, 80% of wastewater enters our environment without being treated, filtered or reused. Wastewater, which contains organic pollutants, inorganic pollutants, textile dyes, pharmaceuticals, faeces, heavy metals and microorganisms, spoils our drinking water and affects our health. Efficient wastewater treatment is a critical requirement for the removal of contaminants in order to maintain a better and safe environment. In this chapter, the use of photocatalysis in previous studies, using various photocatalyst nanocomposites and UV-light and visible light for the removal of numerous pollutants, is reviewed. It is hoped that the use of photocatalytic nanocomposites for environmental remediation will provide the potential to minimize these environmental issue in the future.
