Modulating ion migration realizes both enhanced and long-term-stable nanozyme activity for efficient microplastic degradation.

ABSTRACT: Degradation of microplastics represents a significant global environmental challenge, necessitating the development of bio-inspired catalysts with superior activity and stability, capable of mimicking natural plastic-degrading enzymes. Although nanozymes possess advantages such as low cost, ready availability, and multienzymatic activities, issues of self-consumption often hinder their practical application. Here, motivated by the acceleration of Li⁺ migration for improving the electrochemical reactivity and cycling stability of lithium iron phosphate (LFP), we engineered LFP by introducing Mn²⁺ to expand the lattice structure, resulting in Mn-doped LFP (LFMP) that modulates ion migration in nanozymes. Density functional theory (DFT) calculations reveal that Mn²⁺
