Highly Water-Stable Zinc Based Metal-Organic Framework: Antibacterial, Photocatalytic Degradation and Photoelectric Responses.

A reported water-stable ([Zn(L)(bpa)(HO)]·2HO, HL = 5-(2-cyanophenoxy) isophthalic acid has been prepared via a low-cost, general and efficient hydrothermal method. It is worth noting the structural features of which exhibit the unsaturated metal site and the main non-covalent interactions including O⋯H, N⋯H and π-π stacking interactions, which lead to strong antibacterial and good tetracycline degradation ability. The average diameter of the inhibition zone against and was 12.22 mm and 10.10 mm, respectively. Further, the water-stable can be employed as the effective photocatalyst for the photodegradation of tetracycline, achieving results of 67% within 50 min, and it has good cyclic stability. In addition, the photodegradation mechanism was studied using UV-vis diffuse reflection spectroscopy (UV-VIS DRS) and valence-band X-ray photoelectron spectroscopy (VB-XPS) combined with the ESR profile of , which suggest that ·O is the main active species responsible for tetracycline photodegradation. Also, the photoelectric measurement results show that has a good photocurrent generation performance under light. This provides us with a new perspective to investigate materials as a suitable multifunctional platform for future environmental improvement applications.
