Summary

Tiny plastic particles called micro- and nanoplastics are showing up everywhere, including in our bodies, and scientists are searching for ways to break them down. This review paper (which summarizes existing research rather than presenting new experiments) looks at a promising material called MXene that can absorb plastic particles and use light to help chemically destroy them. While the technology is still being developed and isn't yet ready for widespread use, it points to a potential future tool for cleaning up plastic pollution before it accumulates in our water, food, and bodies.

The environment and public health are seriously threatened by the exponential rise in plastic pollution, especially that which takes the form of micro- and nano-plastics (MNPs). Researchers across the globe have developed promising methods to reduce plastic pollution at the microscopic level by utilizing MXenes due to their remarkable adsorption abilities and photocatalytic activity. This chapter reviews the synthesis and characterization of MXene-based photocatalysts for plastic degradation with special emphasis on important factors including MXene composition, shape and heterostructure design. Furthermore, the potential environmental impact and scalability of MXene-based photocatalytic systems for plastic remediation are evaluated, along with challenges and future directions in this field. Overall, the chapter highlights the exciting potential of MXene-based smart materials as a cutting-edge and environmentally responsible way to tackle the problem of MNP pollution, providing information on the development and application of sophisticated photocatalytic systems for environmental remediation.
