Summary

Researchers reviewed how carbon nanotubes — cylindrical structures made of carbon atoms — can be added to light-activated catalysts to dramatically improve the breakdown of microplastics and nanoplastics in water, as the nanotubes increase surface area and help separate electrical charges that drive the chemical degradation reactions.

The Chemistry of Carbon Nanotubes in Photocatalytic Degradation of Micro-and Nano-PlasticThe proliferation of micro-and nano-plastics in the surrounding shows a substantial hazard to environmental stability and human wellness.Conventional methods for degrading plastic are in effective and harmful to environment.Thus, the emergence of advanced resources for efficient plastic degradation is imperative.Carbon nanotubes (CNTs) have emerged as promising candidates because of their distinctive structural and electronic properties.This paper presents a comprehensive review of the recent advancement in utilizing CNTs as smart materials for photocatalytic degradation of micro-and nano-plastics.The synergetic effects between CNTs and photocatalytic material enhance the degradation efficiency by promoting adsorption, increasing surface area and facilitating charge separation.Various strategies for incorporating CNTs into photocatalytic systems, including hybrid composite and functionalization techniques, are discussed.Furthermore, the mechanisms underlying the photocatalytic degradation processes are elucidated, highlighting the role of CNTs in enhancing photocatalytic activity and selectivity.Challenges and future perspectives for the practical application of CNT based photocatalysts in plastic degradation are also addressed.
