“…FTIR analysis can reveal some evidence to further confirm the interaction between cellulose and Fe 3 O 4 nanoparticles. As illustrated in Figure 3 , the FTIR spectra of native cellulose, MAC, and MAFCC show the characteristic peaks of cellulose at 3428, 2921, 1437, 1378, and 1046 cm ‒1 , corresponding to the O‒H stretching vibration, C‒H stretching vibration, C‒H banding vibration, C‒H deformation vibration, and C‒O stretching vibration, respectively [ 12 , 26 ]. These characteristic peaks of cellulose were also observed on the spectra of Fe 3 O 4 @MAC and Fe 3 O 4 @MAFCC nanocomposites ( Figure 3 e,f).…”

“…As reported in many studies, hydroxyl radicals (•OH) are the master active species in the whole heterogeneous Fenton degradation process, which display a much higher oxidation potentials than •O 2 − and •OOH [ 12 , 38 ]. Tert-butanol is a common radical scavenger to determine whether the catalytic degradation involved •OH.…”

“…For instance, Jiao et al [ 11 ] immobilized Fe 3 O 4 nanoparticles onto cellulose aerogel to prepare Fenton-like catalyst by a hydrothermal method, which displayed a higher degradation rate for Rhodamine B than pure Fe 3 O 4 nanoparticles. The approach was simply described that cellulose hydrogels were immersed in a mixed iron solution for 24 h in the existence of CH 3 COONa and PEG-4000, and then were heated to 200 °C for 8 h. Qin et al [ 12 ] adopted cellulose nanospheres to support Fe 3 O 4 nanoparticles through adding two alkaline solutions. Cellulose was treated in NaOH solution for 8 h, and then the composite was precipitated with ammonia aqueous solution.…”

To rapidly obtain a stable Fe3O4@cellulose heterogeneous Fenton catalyst, a novel in situ chemical co-precipitation method was developed. Compared with mechanical activation (MA)-pretreated cellulose (MAC), MA + FeCl3 (MAFC)-pretreated cellulose (MAFCC) was more easily dissolved and uniformly distributed in NaOH/urea solvent. MAFCC and MAC solutions were used as precipitators to prepare Fe3O4@MAFCC and Fe3O4@MAC nanocomposites, respectively. MAFCC showed stronger interaction and more uniform combination with Fe3O4 nanoparticles than MAC, implying that MAFC pretreatment enhanced the accessibility, reactivity, and dissolving capacity of cellulose thus, provided reactive sites for the in situ growth of Fe3O4 nanoparticles on the regenerated cellulose. Additionally, the catalytic performance of Fe3O4@MAFCC nanocomposite was evaluated by using for catalytic degradation of methylene blue (MB), and Fe3O4@MAC nanocomposite and Fe3O4 nanoparticles were used for comparative studies. Fe3O4@MAFCC nanocomposite exhibited superior catalytic activity for the degradation and mineralization of MB in practical applications. After ten cycles, the structure of Fe3O4@MAFCC nanocomposite was not significantly changed owing to the strong interaction between MAFCC and Fe3O4 nanoparticles. This study provides a green pathway to the fabrication of a stable nanocomposite catalyst with high catalytic performance and reusability for the degradation of organic pollutants.

“…However, M s of 58.583 emu/g was still close to the reported values in current references. [11] Further, the remnant magnetization (M r ) decreased from 1.5705 to 0.95825, and nanocomposites did not show hysteresis loops as seen in the curve. From these results, it is clear that Fe 3 O 4 /PDDA nanocomposites were also superparamagnetic.…”

Superparamagnetic iron oxide particles with average size less than 20 nm were prepared by chemical co‐precipitation method in the air atmosphere. After that, polydimethyldiallyl ammonium chloride (PDDA) was used for wrapping iron oxide particles to obtain the core/shell nanocomposites. The parameters influencing properties of iron oxide particles and iron oxide/PDDA nanocomposites were investigated and optimized. The prepared iron oxide and nanocomposites were characterized by X‐ray diffraction (XRD) measurement, transmission electron microscopy (TEM), particle size and Zeta potential analyzer, Fourier transform infrared (FTIR) spectroscopy, and vibrating sample magnetometry (VSM), respectively. It was found that the iron oxide particles are cubic inverse spinel Fe3O4 with spherical shape. Superparamagnetic behavior of Fe3O4 with 73.114 emu/g is produced with NH4OH as precipitator, and decreased to 58.583 emu/g for Fe3O4/PDDA nanocomposites. The Zeta potential of nanocomposites is positive value. The results showed that Fe3O4/PDDA nanocomposites have excellent future using as a carrier for bonding with some negative charged particles.
