“…Figure 4 b,c display the high-resolution O 1s XPS spectra. The binding energies at around 530.1 and 532.9 eV were attributed to Fe‒O bonds with area peak of 38.7% and C‒O bonds with area peak of 61.3% for Fe 3 O 4 @MAC nanocomposite [ 29 , 30 ]. The O 1s spectrum of Fe 3 O 4 @MAFCC was also deconvoluted to two peaks, which were Fe‒O bonds (39.8%) and C‒O bonds (60.2%).…”

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.

“…Recently, several catalyst supports have been studied such as clays, [15][16][17] hydrogels, [18][19][20] among others. [21][22][23] Other studies use iron-bearing solid catalysts that are naturally iron rich materials, including iron oxides such as goethite (a-FeOOH), 24,25 ferrihydrite (Fe 5 HO 8 $4H 2 O), 26 lepidocrocite (g-FeOOH), 27 hematite, 28 and magnetite (Fe 3 O 4 ). [28][29][30] Most of these supports are raw materials; however, few studies deal with the use of wastes as catalyst for AOPs.…”

Environmental application of an industrial waste as catalyst for the electro-Fenton-like treatment of organic pollutants

2015

The application of acid mine drainage sludge (AMDS), an industrial waste with high metal content, as catalyst for the electro-Fenton-like technology on the treatment of organic polluted effluents has been investigated. The study has demonstrated the potential use of this waste using dye Lissamine Green B as a model contaminant, which allowed the optimization of sludge dosage and pH. AMDS proved to perform a high decoloration rate at pH 2, however, acidic conditions favored metal leaching. Alginate gel beads were selected to immobilize AMDS and to avoid metal release and the wash out of the reactor operating in continuous mode. This developed catalyst showed high reliability and efficiency in successive batches. The efficacy of the established treatment was also verified on the degradation of pesticide pirimicarb and a degradation pathway was determined by LC-MS studies.
