Summary

Researchers designed copper single-atom nanozymes inspired by natural laccase enzymes and tested their ability to degrade microplastics. The bioinspired catalysts mineralized more than 90% of microplastic material into non-toxic products. The study presents a promising new strategy for addressing microplastic pollution using engineered nanoscale catalysts.

Copper single-atom-loaded graphitic nitride nanozymes (Cu SAs) were constructed by bioinspired rational design from natural laccase and density functional theory calculations. Theoretical investigation revealed the geometrical and electronic structural advantages of the Cu-N active center. Experimental tests confirmed the excellent performance in microplastic degradation, with more than 90% mineralized into non-toxic products, providing a new strategy for microplastic pollution management.
