Abstract

Methylene blue pollutants can be treated by photocatalytic methods using metal oxide-based semiconductor materials and metal organic framework (MOF). These two materials are often coupled into a composite to improve their physicochemical properties and catalytic activity. This research focuses on the synthesis of composites based on Cr-PTC MOF, ZnO, and Fe3O4 by the sonochemical method. The obtained composites were characterized and tested for catalytic activity in methylene blue pollutant degradation in an aqueous system under acidic conditions (pH = 5). Our investigation shows that the Cr-PTC@Fe3O4 composite possesses the lowest band gap energy of 1.86 eV and achieves the highest photocatalytic activity in methylene blue degradation at solution pH = 5, with a percent degradation of 84.36%. The sonochemical incorporation of Fe3O4 and Cr-PTC MOF is able to fabricate materials in a short time with better photocatalytic activity in degrading methylene blue than the single materials.

Abstract

Disposal of synthetic dye waste, including methylene blue, has been increasing in recent years. The photocatalytic method is an effective approach for degrading dyes, using Metal–Organic Frameworks (MOFs) as catalysts and light as the energy source. This study aims to synthesize Cu-PTC MOF as a photocatalyst and evaluate its performance in degrading methylene blue dye. Cu-PTC was synthesized using Cu(NO3)2.3H2O and perylene-3,4,9,10-tetracarboxylic dianhydride (PTCDA) via a solvothermal method. The resulting MOF was characterized using X-ray Diffraction (XRD), Ultraviolet–Visible Diffuse Reflectance Spectroscopy (UV-Vis DRS), Fourier Transform Infrared Spectroscopy (FTIR), and Scanning Electron Microscopy (SEM). Cu-PTC exhibits a bandgap energy of 1.72 eV and characteristic functional groups at wavenumbers 1689 cm-1 (C=O), 1590 cm-1 and 1360 cm-1 (-COO), 3450 cm-1 (O-H), and 738 cm-1 and 654 cm-1 (Cu-O). The Cu-PTC MOF has a crystallinity degree of 85.35%, a crystal size of 35.33 nm, and a rod-like surface morphology. Under visible light irradiation, it achieves an optimum degradation efficiency of 71.45%, with an adsorption capacity of 73.28 mg/g for methylene blue dye at a concentration of 50 ppm, using 25 mg of Cu-PTC MOF at pH of 7 over a period of 60 minutes.
