| 英文摘要 | Carbon-coated nanoscale zero-valent iron (Fe@C) is a robust active material in wastewater treatment. Small particle size and high content of zero valent iron nanoparticles (Fe degrees NPs) in Fe@C composites ensure their desired activity in Fenton-like reaction. We mechanochemically prepared Fe-ethylenediaminetetraacetic acid (Fe-EDTA), Fe-aminoterephthalic acid (Fe-ATA), and Fe-melamine (Fe-MA) complex as starting materials to synthesize Fe@C. The coordination ability between iron and ligands determines the particle size and distribution of Fe NPs. Fe@C derived from Fe-EDTA possessed 97.6 % of Fe NPs (4 nm-in-diameter), exhibited strong catalytic ability for sulfamethazine removal with and without the addition of H2O2, but also encountered serious erosion and poor reusability. Fe@C generated from Fe-ATA manifested reasonable activity and excellent stability and reusability in Fenton-like reaction, which was contributed by the suitable particle size (6 nm) and special topological structure. Fe@C-MA produced from Fe-MA exhibited bad catalytic performance and reusability due to its larger Fe NPs size (300 nm). |
