- Abstract
Recyclable foam-sponge construction wood (FSC-wood) with a three-dimensional porous cellulose framework exhibits excellent renewability and availability in various fields. Considering this, herein, we report a novel FSC-wood-based MoS2 and Fe3O4-doped catalyst named MoS2@Fe3O4@FSC-wood made by a facile hydrothermal method to efficiently activate persulfate (PS). MoS2 and Fe3O4 were utilized to improve the catalytic and mechanical performance of FSC-wood. In the meantime, the cellulose structural wood had been applied to anchor catalyst powder and catalytic residue. It was found that the catalytic performance was fully exerted by the combination of wood and dispersed catalyst. For example, 50 mL TC (20 mg mL−1) was degraded 83% in 10 min at pH 6.98. Also, the recovery problem was solved as shown in the process of reuse due to the interaction between MoS2@Fe3O4 and FSC-wood. In addition, the bound Fe (II)/Fe (III), Mo (VI)/Mo (IV), and S2−/S22− showed the possible degradation mechanisms in the cellulose frame. Most important of all, this work proposes a novel strategy for expanding the applications of the MoS2@Fe3O4@FSC-wood system to explore the gap between theory and practice. This research shows that the resulting MoS2@Fe3O4@FSC-wood cellulose sensor is highly efficient, easily recycled, and convenient, making it an attractive material for TC removal.
