Interface engineering of Zr4+-modified FeOOH/CC cathode boosts electrocatalytic peroxymonosulfate activation toward microplastic degradation
AI summary Read the abstract
Researchers engineered a Zr4+-modified FeOOH/carbon cloth cathode using constant-current electrodeposition and self-assembly to overcome interfacial electrostatic repulsion between the cathode and peroxymonosulfate (PMS), enhancing electrocatalytic PMS activation for microplastic degradation. The electrode achieved 73% degradation of polyethylene microplastics within 3 hours under neutral conditions and demonstrated broad-spectrum degradation of polypropylene, polystyrene, and other microplastics above 65% efficiency.
本文通过恒流电沉积与自组装法构建了具有双功能层结构的Zr4+-FeOOH/CC阴极, 提出“阳离子吸附层”策略, 通过引入Zr4+选择性吸附层有效逆转阴极与过一硫酸盐（PMS）之间的界面静电斥力, 显著增强了PMS在反应界面的富集效应. 该电极在中性条件下表现出优异的PMS电催化活化性能, 实现了对聚乙烯微塑料(PE-MPs)的高效降解(73%), 并在3 h内使颗粒表面形成明显蚀刻形貌, 证实了该材料的强氧化能力. 该体系对聚丙烯(PP)、聚苯乙烯(PS)等多种微塑料均具备广谱降解能力(>65%), 在实际水体中仍保持良好性能, 展现实际应用潜力. 本研究为突破电催化活化PMS中界面传质瓶颈提供了新的界面工程思路.
