Catalytical Degradation of Industrial Dyes using Biosynthesized Nanoparticles - Review

Abstract

The rapid growth of the textile industry has led to a surge in the release of industrial dyes, posing a severe environmental threat. An attempt was made in this review paper to explore the catalytical degradation of industrial dyes using biosynthesized nanoparticles as a promising avenue for sustainable remediation and to provide a thorough understanding of the advancements, challenges and potential applications of this innovative approach. The synthesis methods of biosynthesized nanoparticles were explained, highlighting the use of natural extracts and their inherent catalytic properties. A critical analysis of the catalytic degradation process was presented, examining the diverse range of industrial dyes targeted by biosynthesized nanoparticles. The factors influencing degradation efficiency, such as nanoparticle size, composition and the nature of the dye pollutants were investigated and the kinetics and mechanisms governing catalytic degradation were explored, shedding light on the intricacies of the reaction pathways. The environmental impact and sustainability of biosynthesized nanoparticles for dye degradation were thoroughly evaluated. Comparisons with conventional remediation methods were made, emphasizing the eco-friendly nature and potential scalability of this innovative approach. Moreover, challenges and future directions in this field were outlined to guide further research efforts.
