Abstract
A novel Mn-doped Fe-based metal–organic framework (MOF) Fenton-like catalyst was prepared for the removal of wastewater organic pollutants. The catalyst exhibited good degradation performance, stability, and recyclability for the removal of phenol from water with a maximum catalytic efficiency of 96%. Incorporating a long persistent phosphor in the MOF ensured optimum performance in the dark.
Highlights
The Fenton oxidation process has been recognized for some time as a promising and effective method for the treatment of toxic, refractory, and non-biodegradable wastewater organic pollutants.[1−3] The hydroxyl radical (OH) is the main reactive species in the Fenton reaction, which, owing to its nonselective nature, can attack many organic pollutants
X-ray diffraction (XRD) was used to characterize the crystal structure of the synthesized MIL-88BFe catalyst doped with 8% Mn
The Mn-doped metal−organic framework (MOF) exhibited the same characteristic XRD pattern as MIL-88B-Fe and with almost no decrease in intensity, indicating that the crystal structure did not change after manganese doping
Summary
The Fenton oxidation process has been recognized for some time as a promising and effective method for the treatment of toxic, refractory, and non-biodegradable wastewater organic pollutants.[1−3] The hydroxyl radical (OH) is the main reactive species in the Fenton reaction, which, owing to its nonselective nature, can attack many organic pollutants. There is still a demand for the design and preparation of catalysts with effective exposed active sites.[6−8]
