| Popis: | Three novel transition metal complexes, [Co(L)(Cl)(H2O)]·3H2O (1), [Cu(L)2]·5H2O (2) and [Ni(L)2]·8H2O (3) were synthesized at hydrothermal conditions based on ligand (HL: 2,6-bis(2-pyrazinyl)pyridine-4-benzoic acid) and transition metal Co(II), Cu(I), Ni(II) salts. All the complexes were characterized by elemental analysis, IR spectroscopy, UV–Vis spectroscopy and powder X-ray diffraction (PXRD). The X-ray single crystal diffraction showed that complexes 1 and 2 are 2D planar structures and complex 3 is a 1D chain structure. In addition, we investigated the photocatalysis performance of the complexes 1–3, which degraded organic dyes methylene blue (MB) under UV–Vis irradiation. According to the experimental phenomenon, compared with the other complexes, complex 1 achieved a higher photocatalytic activity, after photocatalyzing for 80 min, the degradation rate of dye is as high as 96%. |
