Abstract

Provided are a The molecular formulas are as follows: [Cu(3-bpah)(5-MIP)].2H20; [Ni(3-bpah)(5-MIP)].H20; [Co(3-bpah)(5-MIP)].H20; [Cu(4-bpah)(5-MIP)(H20)]; [Ni(4-bpah)(5-MIP)(H20)].H2O; [Co(4-bpah)(5-MIP)]. Transition metal chlorides, semi-rigid bispyridine bisamide ligands and 5-methyl isophthalic acid are added into deionized water, after pH adjustment, the above mixture is reacted under hydrothermal conditions, and products are obtained. The transition metal compounds are advantageous in that the transition metal compounds have a simple synthetic method, have strong affinity to organic pollutants of methylene blue, methyl orange and rhodamine B, and have good catalytic degradation effects.

Problems solved by technology

Although some transition metal complex materials with excellent properties and novel structures have been synthesized by hydrothermal technology so far, not only transition metal ions will affect the structure and performance of such hybrid materials, but also nitrogen-containing heterocyclic ligands The change of species is also an important factor determining the final structure and performance of functional complexes. The inherent structural characteristics of nitrogen-containing heterocyclic ligands will restrict the synthesis of such functional complexes, such as ligand flexibility, ligand length, coordination The number of points, etc.; therefore, it is still difficult to effectively design and synthesize complex materials with specific functions

[0003] At present, among the nitrogen-containing heterocyclic organic ligands used to construct transition metal functional complexes, ligands containing pyridine groups account for the largest proportion, but the pyridine functional group only plays a role in coordinating with transition metals, resulting in the formation of The complex is hydrophobic, so it has poor affinity for water-soluble organic pollutants and poor catalytic degradation effect

In addition, the known functional complexes as photocatalysts usually have a good degradation ability to a specific organic pollutant in wastewater, but cannot catalyze multiple organic pollutants at the same time, and the catalytic ability has limitations.
