Abstract

We describe a novel procedure to fabricate a recyclable hybrid-photocatalyst based on Bi 2 O 3 @HKUST-1 MOF porous thin films. Bi 2 O 3 nanoparticles (NPs) were synthesized within HKUST-1 (or Cu 3 (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 Bi 2 O 3 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.
