Synthesis of iron based-metal-organic framework nanocomposite and visible light pollutant degradation ability
2021
Abstract Herein, Materials Institute Lavoisier (MIL) metal-organic framework (MOF) including NH2-MIL-101(Fe): NM-101), and NH2-MIL-101(Fe)/phosphotungstic acid (PA) composite with different amounts of PA (1, 2, and 3 g denoted as NMP-1, NMP-2, and NMP-3, respectively) were synthesized and used for light-emitting diode (LED) visible-light degradation of dye (Methylene Blue: MB) solution. The materials were characterized using FTIR, SEM, TEM, TGA, XRD, and PL. The data presented that the NMP-2 composite had the highest degradation ability. The degradation efficiency of NMP-2 for 50 and 110 mg/L of pollutant concentration was 99 % and 55 %, respectively. The degradation kinetics for 0.006 g of NMP-2 followed the zero-order kinetics with 0.0179 min−1 rate constant with high correlation (0.9558).
