Abstract

Metal-Organic Frameworks (MOFs) is widely utilized as photocatalysts in dye photocatalytic degradation. This study successfully synthesized bimetallic MOFs La-Y-PTC by the solvothermal method. The synthesized La-Y-PTC has a diffractogram pattern with a value of 2θ = 5.69°; 9.57°; 16.8°; 20.05°; 24.8°; 26.15°; 29.77° and 41.93° with a crystal size of 21.45 nm. The La-Y-PTC has symmetric and asymmetric (COO−) at 1591 and 1433 cm−1, La−O and Y−O groups at 596 and 659 cm−1 and a band gap energy of 2.16 eV. Scanning Electron Microscope analysis showed that the morphology of La-Y-PTC is spherical with a particle size of 354.307 nm. La-Y-PTC degrades methylene blue and methyl orange at pH 2 with a degradation efficiency of 69.57% and 93.63%, respectively, under 250 watts of mercury lamp irradiation for 180 min with hydroxyl radical species as a dominant species that play a role in methylene blue and methyl orange degradations.

Abstract

Metal Organic Framework (MOF) is a material that serves as a photocatalyst for decomposing methylene blue pollutant. MOF can be constructed using several kinds of synthetic methods. This study aims to determine the alternative efficient and eco-friendly synthesis method of isonicotinic acid-modulated chromium perylene 3,4,9,10-tetracharboxylate MOF (Cr-PTC-HIna) using solvothermal, hydrothermal, sonochemical, and mechanochemical methods. FTIR analysis revealed that Cr-PTC-HIna was successfully fabricated only by solvothermal, hydrothermal, and sonochemical methods, yielding 40.68%, 44.27%, and 46.50%. Cr-PTC-HIna-ST, Cr-PTC-HIna-HT, and Cr-PTC-HIna-SC have band gap energies of 2.02, 2.02, and 1.98 eV, respectively. Cr-PTC-HIna-HT and Cr-PTC-HIna-SC with irregular shapes form agglomerations. Cr-PTC-HIna-SC had the highest surface area, pore volume, and pore size of 92.76 m2.g−1, 0.3947cm3.g−1, and 142.74 nm, respectively. Cr-PTC-HIna-SC has the highest percentage of methylene blue decolorization through adsorption of 61.843% and photocatalytic degradation of 25.635%. Sonochemical and hydrothermal showed potential as more eco-friendly methods than solvothermal in synthesizing Cr-PTC-HIna MOF. Copyright © 2023 by Authors, Published by BCREC Group.

Abstract

Methylene blue is widely used in the textile industry and is difficult to degrade naturally because of its heterocyclic aromatic structure. One technique that can be used to degrade methylene blue is through a photocatalytic process using ZnO nanoparticles. This study aims to synthesize ZnO nanoparticles using Lidah mertua extract (Sansevieria trifasciata) as a capping agent by the sol-gel method, and determine the characteristics and stability of ZnO nanoparticles in methylene blue photodegradation. The synthesis of ZnO nanoparticles begins with drying Lidah mertua, grinding it, and then extracting it using distilled water. Furthermore, the extract was reacted with Zn(CH3COO)2.2H2O 0.15 M at pH 8. The extract was characterized using Fourier Transform Infrared (FTIR), and the ZnO nanoparticles were characterized using X-Ray Diffraction (XRD), ultraviolet-visible (UV-Vis) DRS, and Scanning Electron Microscopy (SEM). Lidah mertua extract has OH (hydroxyl), CN, CH, and C=C functional groups. The obtained ZnO nanoparticles have a crystal size of 19.324 nm. The crystalline phase is hexagonal; the morphology is spherical, with a particle size of 79.153 nm and a band gap energy of 3.21 eV. ZnO nanoparticles exhibited a methylene blue decolorization of 98.50% through 43.41% by adsorption and 55.09% by photocatalytic mechanism. ZnO nanoparticles showed good stability for a three-cycle reaction. Copyright © 2023 by Authors, Published by BCREC Group.

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

Ethylene glycol, a crucial compound extensively utilized in solvents, coolants, antifreeze, polyester fiber production, and as a natural gas-drying agent, can be synthesized via the hydrogenation of ethylene carbonate. In this study, the synthesis, characterization, and catalytic performance of Cu-Ni/SiO2 catalysts for this reaction, utilizing silica (SiO2) derived from rice husk ash, were investigated. Silica was impregnated with copper (Cu) and nickel (Ni) by varying the weight ratio (Cu:Ni = 10, 7:3, 3:7, 10) to prepare bimetallic catalysts. X-ray Diffraction (XRD) analysis confirmed the presence of both Cu and Ni phases in all the catalysts. The 3Cu7Ni/SiO2 catalyst displayed the lowest reduction temperature and the largest surface area (257.97 m²/g). The 7Cu3Ni/SiO2 catalyst exhibited the highest acidity (1.91 mmol/g) and superior metal dispersion, as confirmed by the Field Emission Scanning Electron Microscopy - Energy Dispersive X-Ray (FE-SEM-EDX) analysis. Catalytic activity was evaluated in a batch reactor under 40 bar H2 pressure at 150 °C for 3 h with a catalyst-to-ethylene carbonate ratio of 5:1. Among the catalysts examined, the 7Cu-3Ni/SiO2 composition demonstrated the highest catalytic performance, achieving 15.14% conversion of ethylene carbonate and 80.51% selectivity towards ethylene glycol.
