Abstract

The invention discloses a compound of a metal organic framework material and a two-dimensional material as well as preparation and application of the compound. The compound is mainly formed by loading the ferrocene-based metal organic framework material on graphite phase carbon nitride with a two-dimensional sheet structure, wherein the ferrocene-based metal organic framework material is formed by compounding a ferrocene-modified metal organic framework material. The preparation of the compound comprises the following steps: weighing raw materials, ultrasonically dispersing the raw materials in a solvent, performing normal-temperature ultrasonic treatment to obtain a uniform dispersion liquid, adding a polyethylene glycol solution, carrying out mixing, and conducting stirring to obtain a uniform dispersion liquid; and adding the uniform dispersion liquid into a lining of a reaction kettle, conducting sealing, and performing reacting at 100 DEG C to obtain a composite material. The composite material formed by loading the ferrocene-modified metal organic framework on the graphite phase carbon nitride effectively prevents the agglomeration phenomenon of nanoparticles of the metal organic framework material, improves the transmission efficiency of photon-generated carriers, and has good sewage treatment performance.

Description

technical field [0001] The invention relates to a compound and its preparation method in the field of heterogeneous advanced oxidation technology catalysis, in particular to the preparation of a metal organic framework material and two-dimensional material compound and its application in water pollution treatment. Background technique [0002] The problem of water pollution is closely related to the development of society and people's lives. Among them, organic pollutants (such as antibiotics, organic dyes, bisphenol A, nitrophenol, etc.) are difficult to be removed by traditional methods such as filtration due to their ultra-high stability in water. , adsorption and biodegradation. Even if the concentration of organic pollutants in water is extremely low, they are still neurotoxic and carcinogenic to humans, so sewage treatment has become one of the major problems that need to be solved urgently. At present, the focus of research on water pollution treatment methods is mai...
