Nanocrystals for Environmental Remediation

Nowadays, environmental pollution is considered a worldwide issue due to its harmful effects on human health and aquaticecologies. The problem arises when contaminants ejected from agricultural, plastic, textile, tanning, paper, and leather industries mixed with cleanwater. Recycling and treatment of wastewater is a crucial factor and scientists are thinking of advanced suitable inexpensive technologies. On the other hand, the common infection’s diseases caused by bacterial content which come through pharmaceutical industries wastewater. The demographic analysis show that the root cause of many illnesses is bacterial infections. Notably, semiconductor-based photocatalysis arises as a promising tool for numerous treatments of environmental systems like air purification, antibacterial purpose, hydrogen evaluation, and purify wastewater. In present chapter, the use of different types of nanomaterials such as metal oxides, nanocomposites, and magnetic materials were discussed for environmental remediation. Furthermore, the photocatalysis and antibacterial treatment were also discussed in detail. This chapter provide the understanding about the use of different nanostructures for wastewater treatment and bacterial disinfection.
