Nanoporous metal-organic framework (MOF-199): Synthesis, characterization and photocatalytic degradation of Basic Blue 41

Add time:07/17/2019    Source:sciencedirect.com

Herein, metal-organic framework (MOF-199) as a nanoporous material was synthesized and characterized using FESEM, EDS, FTIR, XRD, BET and TGA. Basic Blue 41 was used for investigating the photocatalytic activity of MOF-199. The SEM image showed that a nanoporous MOF was synthesized. The effect of catalyst dosage, initial pollutant concentration and pH on decolorization was studied. Contaminant degradation increases by increasing catalyst dose and decreases by initial dye concentration. Decolorization rate decreases by decreasing the pH of solution due to the electrostatic repletion of the cationic dye from the surface of MOF-199. The UV–Vis spectra of dye solution during pollutant degradation by MOF-199 showed that the dye absorbance in visible region of spectrum diminished because of the azo band destruction. The data indicated that the synthesized nanoporous metal-organic framework-199 could be used as a photocatalyst for decolorizing wastewater.
