Abstract

The invention discloses a preparation method of a copper and zinc bi-coordination polymer. The preparation method comprises the steps of firstly, preparing a zinc complex under a solvothermal condition; and then, doping a small amount of copper ions to obtain the copper and zinc bi-coordination polymer. Compared with the existing method, the preparation method disclosed by the invention has the advantages that the reaction effect for catalyzing light degradation of rhodamine B by using a zinc complex catalyst doped with a small amount of the copper ions is better, recycling can be realized, and relatively high catalysis efficiency is kept.

Description

technical field [0001] The invention relates to a preparation method of a coordination polymer, in particular to a preparation method of a copper-zinc double coordination polymer. Background technique [0002] In recent years, with the strengthening of people's awareness of environmental protection, catalytic photodegradation of pollutants has become a very active research direction in the field of photochemistry. Among them, rhodamine B is a kind of artificially synthesized dye with bright pink color, which can cause sarcoma in subcutaneous tissue and is a carcinogen. Rhodamine B has applications in fluorescent dyes, colored glass, special fireworks and firecrackers, and food additives. Therefore, the degradation of organic dye pollutants in water is an important topic. [0003] At present, the main methods for degrading water pollutants include physical adsorption, biodegradation, redox, and catalytic photodegradation. The catalytic photodegradation method has the advan...
