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

As an adsorbent material, Metal-Organic Framework (MOF) provides several advantages, such as large surface area and pore volume, as well as stability in aqueous systems both in acidic, basic, and neutral conditions. The research successfully made a metal organic framework (MOF) from chromium and perylene that was modulated by isonicotinic acid. This was done using three different methods: hydrothermal (Cr-PTC-HIna-HT), solvothermal (Cr-PTC-HIna-ST), and sonochemical (Cr-PTC-HIna-SC). The Cr-PTC-HIna-SC showed the greatest Pb2+ ion adsorption capacity. The optimum adsorption of Pb2+ ions occurred at 150 ppm Pb2+ ion concentration, pH 5, 90 minutes of contact time, and an adsorption capacity of 149.95 mg/g at 35 °C. The dominant adsorption isotherm model is the Langmuir isotherm model with R2 = 0.9867 and follows the pseudo-second-order. The selectivity test showed that Cr-PTC-HIna-SC MOF could adsorb more Cd2+ ions than Pb2+ ions, with 250 mg/g being the best amount.

Abstract

Methylene blue wastewater from the paper, clothing, and textile industries can adversely affect aquatic ecosystems if improperly treated. One method to treat methylene blue pollutants in sewage is through photocatalysis techniques using magnesium ferrite (MgFe2O4) nanoparticle-based semiconductors. The MgFe2O4 is effective for methylene blue degradation because it is stable in aqueous systems, inexpensive, and has good photocatalytic activity. This study aims to synthesize MgFe2O4 nanoparticles with pumpkin seed extract (Cucurbita moschata) as a capping agent through a hydrothermal method. Characterization results show that MgFe2O4 nanoparticles synthesized with the addition of 3 mL pumpkin seed extract have a crystal size of 3.87 nm, cubic spinel structure, average particle size of 29 nm, and band gap energy value of 1.94 eV. The MgFe2O4 nanoparticles produced optimum degradation efficiency under mercury lamp irradiation with a degradation capacity of 391.98 mg/g at pH 12.

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.

Abstract

This study investigates the role of anthraquinone (AQ) in decomposing coconut husk waste, specifically collected from Banten, to produce pure α-cellulose pulp. The process used sodium hydroxide (NaOH) at 10%, 15%, and 20% concentrations, with 0.1 g of AQ added as a catalyst, and a waste-to-liquid ratio of 1:8 throughout. The goal is to accelerate lignin degradation while protecting cellulose in the material, thereby yielding higher-quality pulp. The Banten coconut husk analysis showed an α-cellulose content of 30.38%. Higher NaOH concentrations reduced pulp yield but increased lignin removal, indicated by lower kappa numbers. AQ addition enhanced lignin removal and preserved cellulose compared to the absence of AQ. The optimal outcome was achieved with 15% NaOH and 0.1 g AQ, balancing lignin removal and cellulose preservation. These findings indicate that anthraquinone can support sustainable pulp production from agricultural waste. Copyright © 2026 by Authors, Published by BCREC Publishing Group.
