Abstract:

Constructing abundant interfaces in composite catalysts to promote their synergistic effects is the key, though a tough challenge for enhancing photo-Fenton catalysts performance. Herein, a pore-confinement strategy is proposed to construct plasmonic Z-scheme PGDY@MIL(Fe/Cu) for ultra-fast removal dinotefuran. Graphdiyne was grown on Cu sites of MIL(Fe/Cu) and formed nano-elliptical graphdiyne (PGDY) nanosheets within the confinement of pores, while the C-Cu interfacial channels were constructed to promote electron transfer in the catalytic process. Upon illumination, PGDY strongly coupled with the incident light and localized surface plasmon resonance (LSPR) could be excited, thus enhancing light absorption efficiency of PGDY@MIL(Fe/Cu) at 375–600 nm and inducing numerous hot electrons. These unique properties accelerated separation efficiency of PGDY@MIL(Fe/Cu) for photogenerated carriers, which boosted the generation rate of active radicals and Fe3+/Fe2+ and Cu2+/Cu+ cycling rates during photo-Fenton catalysis. Finally, PGDY@MIL(Fe/Cu) exhibited excellent catalytic degradation kinetics (99.1 % within 40 min), mineralization efficiency (98 % within 2 h), and catalytic cycling stability for dinotefuran (DNT) compared to the reported advanced catalyst. © 2024
