Abstract

We describe a novel procedure to fabricate a recyclable hybrid-photocatalyst based on Bi₂O₃@HKUST-1 MOF porous thin films. Bi₂O₃ nanoparticles (NPs) were synthesized within HKUST-1 (or Cu₃(BTC)₂) surface-mounted metal-organic frame-works (SURMOFs) and characterized using X-ray diffraction (XRD), a quartz crystal microbalance (QCM) and transmission electron microscopy (TEM). The Bi₂O₃ semiconductor NPs (diameter 1-3 nm)/SURMOF heterostructures exhibit superior photo-efficiencies compared to NPs synthesized using conventional routes, as demonstrated via the photodegradation of the nuclear fast red (NFR) dye.
