Visible Light-Driven Selective Organic Degradation by FeTiO3/Persulfate System: the Formation and Effect of High Valent Fe(IV)

Lihan Pan et al.

Summary: The study explores the role of high-valent Fe in persulfate-based heterogeneous reactions using a FeTiO3/persulfate system. It reveals the selective degradation of aromatic compounds by photo-generated Fe(IV) and the formation of a complex between Fe(III) and SO(4)(2-) under dark conditions. The study calls for a re-evaluation of the oxidation mechanism in persulfate-based reactions.

Efficient heterogeneous acid synthesis and stability enhancement of UiO-66 impregnated with ammonium sulfate for biodiesel production

Hui Li et al.

Summary: Sulfuric zirconia is a potential heterogeneous acid catalyst for esterification in biodiesel production, but faces challenges in catalytic stability. By using UiO-66 and ammonium sulfate, a high efficient acid catalyst was synthesized, with 'two-stage calcination' to enhance stability. The catalyst prepared under nitrogen atmosphere showed higher catalytic activity, achieving 96.2% oleic acid conversion at optimum conditions, and the second calcination reduced conversion decrement by 66.25% within five cycles.

Activation of sulfite by single-atom Fe deposited graphitic carbon nitride for diclofenac removal: The synergetic effect of transition metal and photocatalysis

Zhiwei Zhao et al.

Summary: In this study, a novel bamboo-like porous graphitic carbon nitride material deposited with single-atom Fe was successfully prepared and used for sulfite activation. The synergistic effect of Fe and g-C3N4 significantly enhanced the removal efficiency of diclofenac under visible light irradiation. The main mechanism behind the synergetic effect was found to be the generation of surface Fe-S(IV) complexes, with additional insights into the degradation pathways of diclofenac and the alleviation of its toxicity through successful mineralization of chlorine atoms.

Targeted degradation of dimethyl phthalate by activating persulfate using molecularly imprinted Fe-MOF-74

Su Ding et al.

Summary: The adsorptive and catalytic properties of Fe-based metalorganic framework (Fe-MOF-74) have been improved by molecular imprinting technique for enhanced selective adsorption of DMP. The material showed dominating chemisorption and a 1.5-fold increase in catalytic rate after modification. The synergy of adsorption and catalysis resulted in effective degradation of DMP with three proposed degradation pathways.

One-step fabrication of oxygen vacancy-enriched Fe@Ti/C composite for highly efficient degradation of organic pollutants through persulfate activation

Ruzhen Xie et al.

Summary: In this study, a cost-effective magnetic carbon-supported Fe@Ti composite was synthesized and used as a highly efficient persulfate (PS) activator for wastewater purification. The Fe@Ti/C-4 composite showed the best catalytic performance, effectively degrading Rhodamine B in wastewater. The presence of oxygen vacancies in the composite promoted electron transfer and played a key role in generating reactive oxygen species (ROS) for efficient degradation of organic pollutants.

Carbonized MIL-100(Fe) used as support for recyclable solid acid synthesis for biodiesel production

Hui Li et al.

Summary: The use of carbonized MIL-100(Fe) to support ammonium sulfate for synthesizing magnetic solid acid has led to an optimized catalyst (CIS) with superparamagnetic properties and high conversion rates for biodiesel production. The CIS showed a saturated magnetism of 22 emu/g and achieved a maximum conversion of 95.68% under mild conditions. Even with the presence of water content, the catalyst still maintained a high conversion rate.

Degradation of anthraquinone dye reactive blue 19 using persulfate activated with Fe/Mn modified biochar: Radical/non-radical mechanisms and fixed-bed reactor study

Yue Qiu et al.

Summary: In this study, a heterogeneous activator prepared from sludge-derived biochar modified by Fe/Mn was found to effectively degrade reactive blue dye. Radical and non-radical mechanisms were proposed, with evidence of sulfate radical, hydroxyl radical, and singlet oxygen involvement. Experimental results also showed the potential of the activator in dye removal. Modeling using artificial neural networks showed better prediction results compared to traditional methods, indicating its suitability for engineering applications.

Summary: The study investigated the enhancement of diclofenac (DCF) degradation by Fe(II)-activated persulfate (PS) combined with bisulfite (BS), showing that the introduction of BS in Fe(II)/PS process improved the efficiency and stability of DCF degradation. The main iron species identified were FeHSO3+, Fe2+, and FeOHSO3H+, and the reactive radical for DCF oxidation in the BS/Fe(II)/PS process was confirmed to be SO4·-. The BS/Fe(II)/PS system presented a synergistic effect for rapid and steady DCF degradation, providing an effective and environmentally friendly approach to sewage treatment.
