Defect modulation of MOF-derived ZnFe2O4/CNTs microcages for persulfate activation: Enhanced nonradical catalytic oxidation

Huachun Lan et al.

Summary: There has been increasing interest in combining porous metal organic frameworks (MOFs) with conductive carbonaceous materials to enhance catalytic activity. In this study, a simple strategy was developed to synthesize a highly efficient and recyclable heterogeneous catalyst through the pyrolysis of MOFs as sacrificial templates. The introduction of defective sites in the carbon nanotubes (CNTs) precursor significantly improved the charge transfer capability of the composite microcages and the coordination environment of Fe centers. With the assistance of persulfate oxidants, the modulated defects in ZnFe2O4/CNTs-Ar exhibited a 17.5-fold higher reaction rate for Bisphenol A degradation compared to blank ZnFe(2)O(4) microcages. Experimental characterizations indicated that the defective CNTs facilitated the electron transfer from BPA molecules to persulfate, triggering the direct decomposition of pollutants through a non-radical oxidation pathway. This research provides a new strategy for developing high-performance MOFs-derived catalysts for wastewater treatment.

Jian Sun et al.

Summary: Metal-organic frameworks (MOFs) have been studied for their excellent environmental catalytic capabilities. In this study, a modulation approach using formic acid as a modulator was successfully used to synthesize Fe-based MOFs. The modulated FeMOFs-2 sample showed high specific surface area and catalytic activity, effectively degrading SMX with almost 95% removal efficiency. The addition of formic acid induced the formation of more coordinatively unsaturated metal sites in the catalyst, resulting in structural defects and increased catalytic performance.
