Application of a Mixed-Ligand Metal–Organic Framework in Photocatalytic CO(2) Reduction, Antibacterial Activity and Dye Adsorption

In this paper, a known mixed-ligand MOF {[Co(2)(TZMB)(2)(1,4-bib)(0.5)(H(2)O)(2)]·(H(2)O)(2)}(n) (compound 1) was reproduced, and its potential application potential was explored. It was found that compound 1 had high photocatalytic activity for CO(2) reduction. After 12 h of illumination, the formation rate of CO, which is the product of CO(2) reduction by compound 1, reached 3012.5 μmol/g/h. At the same time, compound 1 has a good antibacterial effect on Staphylococcus aureus (S. aureus), Escherichia coli (E. coli) and Candida albicans (C. albicans), which has potential research value in the medical field. In addition, compound 1 can effectively remove Congo Red from aqueous solutions and achieve the separation of Congo red from mixed dye solutions.
