Zn-Btc Mof As An Adsorbent For Iodine Uptake And Organic Dye Degradation

A porous MOF, [Zn-3(BTC)(2)(H2O)(3)}center dot 2.5H(2)O](n) (H3BTC = 1,3,5-benzenetricarboxylic acid) was synthesized by heating ZnCl2 and H3BTC in DMF at pH 8.2. A single-crystal XRD study reveals a 3D polymeric unit constructed by paddlewheel SBUs. The title MOF displays remarkable iodine uptake in both water and hexane medium (84% and 74%, respectively). The synthesized MOF also reveals heterogeneous catalytic activity toward rhodamine B (RhB) (degradation efficiency 85%) and methylene blue (MB) (degradation efficiency 79%) under visible light in the presence of H2O2.
