Porous CuS-CuPt Nanosheets for Enhanced Photocatalytic Degradation of Organic Dyes
Abstract
Abstract Designing active surfaces to control interfacial reaction dynamics is crucial for advanced water treatment. Herein, we report ultrathin porous CuS-CuPt nanosheets (CuS-CuPt UPNSs) whose limited thickness and high-density pore network create a highly efficient solid–liquid interface for the photo-Fenton degradation of dyes. The porous surface morphology, confirmed by FEM simulations to generate localized electric field hotspots, works in synergy with bimetallic sites to accelerate the production of hydroxyl radicals (•OH) at the catalyst–water interface. This interfacial activity leads to rapid and complete pollutant degradation with sustained catalytic recyclability. Our findings highlight the importance of nanoscale surface engineering in manipulating interfacial charge transfer and radical generation pathways for environmental purification.
