Preparation of Two Transition Metal Coordination Polymers and Their Application as Photocatalysts in Dye Degradation
摘要
In the present study, two transition metal CPs on the basis of Co(II) and Mn(II) ions as the metal centers have been produced in success with reaction between the ligand of 2-(hydroxymethyl)-1H-benzo[d]imidazole-5-carboxylic acid (H2L) and corresponding metal salts under a solvothermal reaction condition, and their chemical formulae are {[Co2(HL)2(H2O)4]·H2O·SiF6}n (2) together with {[Mn2(HL)2(H2O)3(SO4)]·H2O}n (1). They were characterized by PXRD, EA, IR, single-crystal X-ray diffraction, and TGA. Additionally, both complexes exhibited excellent photocatalytic activity in the UV-induced degradation of Rhodamine B, rendering them excellent candidates for dye degradation.
