Cu(II) and Mn(II) coordination polymers [Cu(ttpa)(sub)] ( or ) and {[Mn(ttpa)(nip)(HO)]·3HO} ( or ) (ttpa = tris(4-(1,2,4-triazol-1-yl)phenyl)amine, Hsub = suberic acid, nip = 5-nitroisophthalicate) were hydrothermally prepared and the structures were characterized. exhibited a 2D (4,4) network based on [Cu(COO)] dimers with upper and lower dangled ttpa ligands and a 2D → 3D polythreaded network. showed a 2D (4,4) network with dangled uncoordinated triazole rings from ttpa ligands and nitro groups from nip ligands and a 2D → 3D polythreaded network. data of and were 1.88 eV and 2.11 eV. and exhibited good catalytic activity for the decomposition of methyl blue (MB) under visible light and supersound irradiation. The decomposition mechanism using was explored. The holes (h) and OH hydroxyl radicals played the main roles, and the O superoxide radicals played certain auxiliary roles in the decomposition of MB within the catalyst.
