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.

摘要

我们描述了一种基于Bi2O3@HKUST-1金属有机框架（MOF）多孔薄膜制备可回收混合光催化剂的新方法。Bi2O3纳米颗粒（NPs）在HKUST-1（或Cu3(BTC)2）表面安装的金属有机框架（SURMOFs）中合成，并使用X射线衍射（XRD）、石英晶体微天平（QCM）和透射电子显微镜（TEM）进行表征。与通过传统方法合成的纳米颗粒相比，Bi2O3半导体纳米颗粒（直径1-3纳米）/SURMOF异质结构表现出优异的光效率，这通过核固红（NFR）染料的光降解得到了证明。
