[0023] Preparation of Pd / MIL-100(Fe) Catalyst

[0024] Mix 5 mL of ethanol, 5 mL of water, 0.333 g of polyvinylpyrrolidone, 294 μL of H 2 PdCl 4 (10 mg / mL) was mixed with 0.1 g carrier, stirred for 30 min to disperse evenly, and then refluxed at 90°C for 3 h. Finally, the obtained product was centrifuged, washed with deionized water to remove excess ions, and vacuum-dried at 60°C to obtain a Pd / MIL-100(Fe) composite material. figure 1 The XRD pattern of the Pd / MIL-100(Fe) catalyst synthesized by this preparation method is shown. figure 2 The transmission electron microscope image of the Pd / MIL-100(Fe) catalyst synthesized by this preparation method is shown.

Abstract

The invention discloses a Pd / metal-organic framework compound catalyst as well as a preparation method and application thereof. The preparation method comprises the following steps: dispersing MIL-100(Fe) in an ethanol-water mixed solution, adding polyvinylpyrrolidone and H2PdCl4 under continuous stirring, and performing reflux with an oil bath for 3 h at 90 DEG C so as to obtain the Pd / MIL-100(Fe) composite material, wherein during the process, Pd(2+) can be reduced by ethanol gradually. According to the invention, a simple and mild method for reducing precious metal by ethanol is adopted, high-dispersity precious metal Pd nano-particles grow on MIL-100(Fe) with a super-large specific area, and in the whole process, inert atmosphere, a strong reducing agent and heat treatment process are not required. The prepared Pd nano-particles are good in dispersity, and high in utilization ratio, and have the property of efficiently degrading medicines, personal care products or dyes in the water environment through photocatalysis at the room temperature.

Description

technical field [0001] The invention belongs to the technical field of catalysis in energy and environmental treatment, and specifically relates to a Pd / metal organic framework compound catalyst and a preparation method and application thereof. Background technique [0002] Metal-Organic Frameworks (MOFs) materials are a general term for a class of microporous-mesoporous metal-organic coordination polymers that use metal cations as nodes and organic ligands with multi-dentate coordination as linkers. As a new force of the new generation of porous materials, MOFs materials have the same characteristics as traditional porous materials—porosity, and at the same time, MOFs materials have their own characteristics, such as pore tailorability, modifiability, functionality endowed by metal centers, unsaturated Metal sites and dynamic framework structures make MOFs materials have great application prospects in many aspects such as gas storage and separation, drug delivery, light, el...
