Abstract

The invention relates to a novel metal organic framework molecular material of an electron-rich system. The molecular formula of the metal organic framework molecular material is C27H21CdN9O7, the chemical formula of the metal organic framework molecular material is [Cd(TIPA)(NO3)2].H2O, and the metal organic framework molecular material is called Cd-TIPA (TIPA=tris-(4-imidazolylphenyl) amine) forshort. The compound belongs to a monoclinic system and a C2 space group, and the topological structure is a utp type. The synthesis method specifically comprises the following steps: uniformly mixingCd(NO3)2.6H2O and TIPA in a mixed solvent of distilled water and N,N-dimethyl formamide, then transferring the mixture into a reaction kettle to react for 70-80 hours at 90-100 DEG C, cooling to a room temperature, separating out crystals, washing and drying to obtain Cd-TIPA. The novel metal organic framework molecular material can be used as a photocatalyst for catalytic reduction of heavy metal ions, in particular, Cr (VI) and Mn (VII).

Description

technical field

[0001] The invention belongs to the technical field of preparation of metal-organic framework compounds, and in particular relates to a novel metal-organic framework molecular material with an electron-rich system, a synthesis method and its use as a photocatalyst in the catalytic reduction of heavy metal ions, especially Cr(VI) and Mn(VII). Applications. Background technique

[0002] In recent years, the rapid development of the chemical industry has led to increasingly serious water pollution, especially the widespread use of heavy metals in electroplating, painting processes, mining, and electronics manufacturing. However, heavy metals are mostly highly toxic and carcinogenic, which poses a great threat to the environment and human health. Among them, hexavalent chromium ion Cr(VI) has been identified as one of the most toxic species in these heavy metal pollutions, and the Environmental Protection Agency stipulates that the content of hexavalent chromium...
