However, Fe₃O₄ NPs aggregate easily and have poor dispersion stability because of their magnetic properties, which seriously decrease their catalytic efficiency. In this study, a novel environmentally friendly method for synthesising Fe₃O₄@CA was proposed. Fe₃O₄ NPs were immobilized on the 3D cellulose aerogels (CAs) in order to augment the degradation efficiency of <i>p</i>-nitrophenol (PNP) treatment and make the separation of the catalyst accessible by vacuum filtration method. Besides, CAs were fabricated from a cellulose source extracted from water hyacinth Heliyone22319https://www.ebi.ac.uk/biostudies/studies/S-EPMC10694324biostudies-literatureMagnetite nanoparticles decorated on cellulose aerogel for <i>p</i>-nitrophenol Fenton degradation: Effects of the active phase loading, cross-linker agent and preparation method.PMC10694324Nguyen TTVHo TGTThieu NQNguyen HDTNguyen TNguyen QKKy Phuong Ha HDo BLPham TTPfalseMagnetite nanoparticles decorated on cellulose aerogel for <i>p</i>-nitrophenol Fenton degradation: Effects of the active phase loading, cross-linker agent and preparation method.Magnetite nanoparticles (Fe₃O₄ NPs) are among the most effective Fenton-Like heterogeneous catalysts for degrading environmental contaminants.
