Abstract :

Because of the high costs and secondary pollutants generating from traditional biological and physical treatment methods, scientists have focused on the exploitations of new catalysts recently. Here, two cobalt-dicarboxylate photo-catalysts [Co(4pysmia)(H2O)2]n (1) and [Co3(�¼-OH)(H2O)(pysmiaH)(pysmia)2]n (2) have been hydrothermally synthesized from the reactions of 5-((pyridin-4-ylthio)methyl)isophthalic acid (H2pysmia) with CoSO4. 1 represents a 2D network with a Schl�¤fli symbol of 63. 2 is an unprecedented (3,3,7)-connected network with the Schl�¤fli symbol of (43)(4��82)(4561185). Both 1 and 2 manifest photocatalytic activities for degradation of methylene blue (MB) under UV light irradiation and show good stabilities toward UV-light photocatalysis. Remarkably, the degradation rate of 2 towards MB can reach 91.4%.
