13 - Green and sustainable methods for dye degradation employing photocatalytic materials

Abstract

Synthetic dyes enhance the aesthetic value of the product, which has accelerated the use of synthetic colorants in almost all essential commodities including papers, textiles, foods, polymers, paints, and many more. However, these synthetic colorants need to be degraded concerning their adverse effects on the environment. Among many degradation processes, photocatalytic dye degradation has established itself into this space due to itsr exceptional benefits over conventional methods including less chemical and energy consumption while offering better reusability and economic viability. There is a great demand for high performing, low-cost processes for photocatalytic degradation of dyes. This chapter highlights the various developmental and implicational aspects of photocatalytic materials employed in dye degradation. Finally, it also renders insight into the prospects of a splendid blend of nanotechnology and photocatalysis in the field, while attaining green and sustainable degradation processes.
