Photocatalytic Degradation of Dyes Using Green Synthesized Metal Nanoparticles

Abstract

Environmentally hazardous, synthetic organic substances with a complex structure are known as dyes. A major environmental issue is the removal of dyes from the environment, and many techniques are often employed to break down colors. One thought to be a good replacement for dye degradation is photocatalysis. Various photocatalysts carry out the complete mineralization of colors without generating hazardous by-products. When exposed to UV or visible light, metal nanoparticles' promising catalytic ability allows them to break down dangerous synthetic dyes. Compared to traditional methods, green production of metal nanoparticles is more economical and environmentally benign. This book chapter focuses on using different green synthesized metal nanoparticles to degrade synthetic colors. The photodegradation mechanism presented in this chapter could clarify future uses for dye degradation.

Keywords: Green synthesis, Metal nanoparticles, Photocatalytic degradation, Synthetic dyes.
