Abstract

The invention belongs to the technical field of chemistry and particularly relates to a preparing method and application based on a Ba / Fe / Na metal and carboxylic acid Schiff base complex. The chemical formula of the complex is (BaNa(Fe-L)2(Mu2-OH)(H2O)).DMF.2H2O, wherein L is a 1, 2-cyclohexane diamino-N, N'-di(3-methyl-5-carboxyl salicylaldehyde) negative ion from which four protons are removed. The complex is prepared by adopting a solvent-thermal method. Researches on organic pollutant light catalytic degradation of the complex show that the complex can degrade 2-monochlorphenol, 3-monochlorphenol and 4-monochlorphenol under irradiation of visible light, has the best light degradation efficacy on 4-monochlorphenol, and is expected to be applied to the field of material science as a catalyst for organic pollutant light degradation.

Description

Technical field [0001] The invention belongs to the technical field of chemistry, and specifically relates to a method for preparing a transition metal complex and its application. Background technique [0002] Heterometallic organic frameworks have been widely concerned by chemists due to their potential applications in magnetism, gas adsorption and heterogeneous catalysis (T. Senapati, C. Pichon, R. Ababei, C. Mathonie?re, R. Cle ?rac, Inorg. Chem . 2012, 51, 3796). Functionalized Schiff bases are excellent ligands for the preparation of heterometallic complexes. The reason is that the internal cavity and external functional groups of Schiff bases can coordinate with different metals separately (K. Bhattacharya, SMT Abtab, MC Majee, A. Endo, M. Chaudhury, Inorg. Chem . 2014, 53, 8287). [0003] Photocatalysis is also a current research hotspot. This technology is widely used in the purification and separation of gas and water (H. Zhang, L.-H. Guo, L. Zhao, B. Wan, Y. Yang, J....
