Coordination polymers (CPs) are a diverse class of multi-dimensional compounds that show promise as photocatalysts for degrading dyes in polluted water. Herein, a new 1D Cd(II)-based coordination polymer with the formula [Cd(bpyp)(nba)₂] (1) (bpyp = 2,5-bis(pyrid-4-yl)pyridine and Hnba = 4-nitrobenzoic acid) is synthesized and characterized. In 1, the two carboxyl groups of two different nba⁻ ligands show μ₂-η¹:η¹ and μ₁-η¹:η¹ coordination modes to connect the Cd^II centers and sit on either side of the chain along the b direction. The produced CP 1 was utilized as the photocatalyst in the process of the photodegradation of methyl blue (MB), methyl orange (MO), rhodamine B (RhB), and methyl violet (MV) dyes when exposed to UV light. The photocatalytic degradation activities of CP 1 were analyzed, and the results suggest that it exhibits an extraordinary efficiency in the degradation of MB, MV, MO, and RhB. RhB has a 95.52% efficiency of degradation, whereas MV has a 58.92% efficiency, MO has 35.44%, and MB has 29.24%. The photodecomposition of dyes is catalyzed mostly by •O₂⁻ and •OH⁻, as shown by research involving the trapping of radicals.

The DOX@7FZ was able to enhance the ROS level in cancer cells via a synergistic effect between apoptosis/ferroptosis synergism.

Two highly stable metal–organic frameworks (MOFs) assembled by a flexible 1,4-bis(2-methylimidazol-1-yl)butane (bib), and two different aromatic carboxylate coligands, namely, [Zn(BDC–OH₂)(bib)] (1) and [Cd₃(BTC)₂(bib)(DMF)₃] (2) (H₂BDC–OH₂ = 2,5-dihydroxyterephthalic acid, H₃BTC = 1,3,5-benzenetribenzoic acid), were designed and synthesized. 1 showed a 4-fold interpenetration of 4-connected dia-type topological net. In 2, the 3D topological structure can be viewed as a (3,4,5)-connected network, and its Schläli point is {4·6²}₂ {4²·6·8³} {4⁶·8⁹}. Different auxiliary carboxylate ligands were examined with respect to the building of various structures. 1 and 2 have outstanding photocatalytic behaviors for the disintegration of methyl violet (MV) under UV irradiation.

A new Fe₃O₄-ES/ZIF-8 was synthesized via a facile method and was used to remove the norfloxacin with a high efficiency of 80.13%. The magnetic nature of the adsorbent caused to an easy separation from aqueous solution.
