Intentionally Incorporated Fe Cations in Silverton Polyoxometalates Forming Fenton-like Photocatalysts for Enhanced Degradation

Multifunctional polyoxometalates encapsulated in MIL-100(Fe): highly efficient photocatalysts for selective transformation under visible light.

H3PMo12O40 molecules have been successfully encapsulated in the cavities of MIL-100(Fe) via a facile hydrothermal method (denoted as HPMo@MIL-100(Fe)). A series of characterization has corroborated the insertion of H3PMo12O40 within the cavities of MIL-100(Fe). The resulting HPMo@MIL-100(Fe) nanocomposites have exhibited much higher photoactivity than the original-MIL-100(Fe) toward the photoca...

Efficient Fenton like degradation of Methylene blue in aqueous solution by using Fe3O4 nanoparticles as catalyst

Fe3O4 nanoparticles were prepared hydrothermally and characterized by X-Ray diffraction spectroscopy (XRD), and scanning electron microscopy (SEM). It was found that these nanoparticles can act as an efficient catalyst in the degradation of Methylene blue dye in aqueous solution in a Fenton like system in presence of 30% perhydrol. Uv-Vis spectroscopy was used to determine the concentration of ...

Enhanced degradation of gaseous benzene by a Fenton reaction

A wet scrubbing process coupled with advanced oxidation processes (AOP) has raised great interest for the abatement of volatile organic compounds (VOCs) owing to its strong oxidation capacity and few byproducts. Fenton as an AOP has been widely used in wastewater treatment. However, the dosing method of Fenton reagents is not suitable for the treatment of continuous-flow VOCs waste-gas since H2...

Ultrasound-enhanced polymer degradation and release of incorporated substances.

The effect of ultrasound on the degradation of polymers and the release rate of incorporated molecules within those polymers was examined. Up to 5-fold reversible increases in degradation rate and up to 20-fold reversible increases in release rate of incorporated molecules were observed with biodegradable polyanhydrides, polyglycolides, and polylactides. Up to 10-fold reversible increases in re...
