A new 3D high connection Cu-based MOF introducing a flexible tetracarboxylic acid linker: Photocatalytic dye degradation. (1st November 2021) - Shi, Chunyue
Graphical abstract: Polymer 1 has efficient photocatalytic performances to selectively degrade methylene blue (MB) among the dyes methylene orange and Rhodamine B. A mechanistic investigation toward better discussion of the degradation process of MB was conducted by LC-MS methods. Abstract: Metal-organic frameworks (MOFs) have brought as splendid class of multidimensional materials which can be explored as photocatalytic materials to degrade dyes present in waste-water discharge. Herein, a new MOF namely [Cu3 (L)2 (4, 4′-bipy)] (1 ) (H3 L = 1, 3, 5-tris(4-carbonylphenyloxy)benzene and4, 4′-bipy = 4, 4′-bipyridine), has been prepared and characterized. It was revealed that 1 features a three-dimensional (3, 8)-connected framework with point symbol of (4 2 .6)2 (4 4 .6 10 .7 5 .8 8 .9) topology. The current photocatalysis results indicated that 1 has efficient photocatalytic performances to selectively degrade methylene blue (MB) when compared to the dyes methylene orange and Rhodamine B. A mechanistic investigation toward better discussion of the degradation process of MB was conducted by LC-MS methods.
