Abstract

A novel porous metal organic framework, La-PTC was synthesized by solvothermal method using a perylene-3,4,9,10-tetracarboxylate ligand and lanthanum metal ion. The FTIR analysis showed that La-PTC has a different structure with PTCDA and Na4PTC. The La-PTC MOF has high crystallinity, bandgap energy of 2.21 eV with a maximum absorption area at 561 nm. A rod shape structure of La-PTC has been obtained with the surface area of 22.2364 m2.g−1 and classified into mesoporous material. The La-PTC was relative stable up to 376.93 °C. The La-PTC can degrade 64.76% of MO within ca. 240 min under visible light irradiation with the amount of 30 mg La-PTC. The addition of H2O2 improved the photocatalytic activity of La-PTC with degradation efficiency of 67.02%, 70.00%, and 99.60% for MB, RhB, and MO, respectively. This study presents the fabrication of the light-harvesting metal organic framework, La-PTC and its potential in dyes degradation. Copyright © 2021 by Authors, Published by BCREC Group.

Abstract

A novel responsive visible light Cr-based MOF, Cr-PTC-HIna, was synthesized using the solvothermal method. Cr-PTC-HIna peaks were observed at 2θ = 9.04°, 12.71°, 14.88°, 25,48°, 27.72°, 28.97°, and 43.60° with a crystal size of 21 nm. Band gap energy achieved from the Cr-PTC HIna was 2.05 eV. Scanning Electron Microscope (SEM) analysis obtained a 3D structural morphology of MOFs Cr-PTC-HIna with a cylindrical tube shape and a particle size of 251.45 nm. Cr-PTC-HIna gave the optimum methylene blue degradation at pH of 7 under 250 watts mercury lamp irradiation for 180 minutes with degradation capacity of 95.40 mg/g. Electron holes and hydroxyl radicals were found as the dominant species contributing to methylene blue degradation. Copyright © 2022 by Authors, Published by BCREC Group.

Abstract

Textile industry waste can pollute the aquatic environment because it contains dye contaminants with very stable properties that are difficult to degrade naturally. However, dye contaminants degradation can be carried out by photodegradation using ZnO-Fe3O4 magnetic nanocomposite photocatalysts. This study aims to synthesize ZnO-Fe3O4 magnetic nanocomposite through a sonochemical method. Then measure their photocatalytic activity in methylene blue degradation. The best ZnO-Fe3O4 magnetic nanocomposite is made of ZnO:Fe3O4 mass ratio of 4:1 with a crystal size of 31.058 nm, a hexagonal crystal phase and a particle size of 173.23 nm. The ZnO-Fe3O4 magnetic nanocomposites (4:1) provides optimum degradation capacity of methylene blue under halogen lamp irradiation of 99.56 mg/g at pH 13. Furthermore, the ZnO-Fe3O4 magnetic nanocomposites had good stability in 10 cycles reaction with a degradation capacity of 99.24-99.75 mg/g. The photocatalytic degradation of methylene blue by ZnO-Fe3O4 occurs through the formation of free radical species with hydroxyl radicals as the dominant species that play an important role in the degradation process.
