摘要 | In this work, Prussian blue nanoparticles (PB NPs) were in situ grown on S. cerevisiae cells via one-step hydrothermal synthesis and the as-prepared Prussian blue@yeast (PB@yeast) hybrids exhibited synergistic adsorption and Fenton catalytic activities. FE-SEM, XRD and BET analysis of the prepared samples confirmed the successful formation of hollow porous structured PB@yeast microspheres, while FT-IR and XPS spectra indicated the fine structures were occupied by both functional adsorptive and catalytic sites. The experimental results of adsorption coupled Fenton reaction of PB@yeast hybrid microspheres revealed that the functional groups on the cell wall and the active iron sites in PB framework were fully utilized due to the triple synergistic effects of adsorption-Fenton catalysis-adsorption sites regeneration, thus endowing synergistically enhanced performance in removal of the selected cationic methylene blue (MB), anionic Methyl Orange (MO) and fluorescent brightener 71 (CXT) in aqueous solution. The high Fenton catalytic efficiency was related to the improvement of adsorption, in which the enrichment of contaminant molecules on the outer and inner surface of the hollow porous microspheres could lower mass transfer resistance and shorten charge transport pathways, thereby introducing more efficient Fenton catalytic activity than PB NPs. |
