Uniform N-coordinated single-atomic iron sites dispersed in porous carbon framework to activate PMS for efficient BPA degradation via high-valent iron-oxo species
Abstract
Abstract Iron-mediated activation of peroxymonosulfate (PMS) has been widely investigated for recalcitrant pollutants. However, maximizing the dispersion degree of the active iron sites in the catalysts is still a great challenge and attracting tremendous attention. Herein, we demonstrated that well-dispersed single atomic Fe sites embedded into N-doped porous carbon (FeSA-N-C), which derived from chemically Fe-doped zeolitic imidazolate frameworks, could work as Fe-based catalyst for efficient catalytic oxidation of recalcitrant organics via PMS activation. As expected, FeSA-N-C exhibited remarkably higher degradation activity (8.1 times faster) to BPA (a model pollutant) than that of Fe based nanoparticles-loaded N-doped carbon (FeNP-N-C). The sufficient Fe-Nx sites with single Fe atom as the building units were proposed to be the main active sites for PMS activation. Based on that, unlike the traditional sulfate radical-based advanced oxidation processes, BPA degradation was achieved via high-valent iron-oxo species. More particularly, it could be used over a wide range of pH 3.0–7.5 with almost no loss of degradation efficiency. This study will provide insights into the design of heterogeneous Fenton-like catalysts.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
