Preparation method of spindle-shaped metal organic framework compound grains

Abstract

The invention relates to spindle-shaped metal organic hybridized compound grains MIL-88B(Fe) and a preparation method thereof and belongs to the field of preparation of novel nano photocatalytic materials. A used material synthesis method is a solution method. The method comprises the following specific steps: firstly, dissolving ferric chloride and terephthalic acid (tp) into a mixed solvent of N,N-dimethylformamide (DMF) and acetonitrile; taking a mixed turbid solution to react in an oil bath pot; and centrifuging, washing and drying the obtained product to obtain dark red powdery solids, namely the nano photocatalytic materials. The preparation method provided by the invention is simple, convenient and feasible; and the obtained nano photocatalytic materials have stable performance, have a good degradation performance on organic dyes including Rhodamine B and the like, and have a good application prospect in the fields of environment protection, pollution management and the like.

Description

technical field [0001] The invention relates to a spindle-shaped metal-organic hybrid particle MIL-88B(Fe) and a preparation method thereof, belonging to the technical field of functional materials. Background technique [0002] Metal-organic frameworks (MOFs) compounds have high specific surface area and porosity, and have excellent properties in gas adsorption and catalysis, and have attracted extensive attention. At present, the equivalent research on MOFs materials is concentrated on the macro scale, that is, to synthesize large-sized crystals and study their properties. Research in this area has achieved very valuable results, and a large number of MOFs crystal materials have been prepared. However, there are still some shortcomings in the current research on MOFs materials. Many MOFs materials with excellent performance cannot be effectively applied due to their large size. For example, MOFs materials with excellent fluorescence properties cannot be applied to biolog...
