Abstract:
Plasmonic metal-organic frameworks (plasmonic-MOFs) ingeniously meld the homogeneous and vast porosity of MOFs with the distinctive plasmonic characteristics of metallic nanoparticles (NPs), creating a powerful synergy. This innovative combination is leveraged for enhanced plasmon-induced hot-electron photocatalysis, particularly within polystyrene beads adorned with silver nanoparticles (AgNPs) and encapsulated by zeolitic imidazolate framework-8 (ZIF-8). The strategic incorporation of AgNPs into this composite material generates hot carriers, significantly enhancing the catalytic performance of ZIF-8. This approach not only exemplifies the potential for advanced photocatalytic processes of MOFs, but also paves the way for groundbreaking applications in environmental remediation and sustainable chemistry. Plasmonic metal-organic frameworks combine the extensive porosity of MOFs with the unique plasmonic properties of metallic nanoparticles, enhancing plasmon-induced hot-electron photocatalysis. image
