Synthesis, structure and photocatalytic degradation of organic dyes of a copper(II) metal–organic framework (Cu–MOF) with a 4-coordinated three-dimensional CdSO₄ topology

Abstract

Metal-organic frameworks (MOFs) have attracted much interest in the fields of gas separation and storage, catalysis synthesis, nonlinear optics, sensors, luminescence, magnetism, photocatalysis gradation and crystal engineering because of their diverse properties and intriguing topologies. A Cu-MOF,Á2H 2 O} n , (I), was synthesized by the hydrothermal method using tris[4-(1,2,4-triazol-1-yl)phenyl]amine (ttpa) and succinate (suc 2À ), and characterized by IR, powder X-ray diffraction (PXRD), luminescence, optical band gap and valence band X-ray photoelectron spectroscopy (VB XPS). Cu-MOF (I) shows a twofold interpenetrating 4-coordinated three-dimensional CdSO 4 topology with point symbol {6 5 Á8}. It presents good photocatalytic degradation of methylene blue (MB) and rhodamine B (RhB) under visible-light irradiation. A photocatalytic mechanism was proposed and confirmed. research papers 1054 Qian et al. A Cu II MOF with a 4-coordinated 3D CdSO 4 topology Acta Cryst. (2019). C75

Multiple cobalt active sites evenly embedded in mesoporous carbon nanospheres derived from a polymer-metal-organic framework: efficient removal and photodegradation of malachite green

“…Recently, metal–organic frameworks (MOFs) have shown potential and extensive applications as efficient photocatalysts for adsorbing or degrading pollutants, such as Ti-MOF, 14 Cu-MOF, 15 and Co-MOF, 16 because of their large surface area, tailorable chemistry, and rich functionality. 17 MOF-based catalysts have also exhibited good catalytic ability toward the degradation of organic dyes.…”
