Abstract

En 中文
• A 3D Electro-Fenton/PMS system achieved 62.03% PS-MPs (1 g L-1) degradation at room temperature. • Defect-induced dehydrogenation lowered SO4•- desorption energy (4.77 eV) for PS degradation. • Defect-enabled radical-electron dual pathways drove efficient PS-MPs chain scission. • Only ~4% dissolved organic carbon remained, indicating dominant carbon loss of PS. • 3D electro-Fenton/PMS degraded PS microplastics with only 0.43 kWh g-1 energy input.
